It's time to MASTER Colour Mixing
and transform your paintings!


The Colour Mixing Detective

Stop mixing MUD and solve the mystery of your paints
once and for all.

DEADLINE: Friday March 30, 2018 at midnight.

This is a Toronto technical painting course. Only 4 spots left!

My studio at 401 Richmond St. West is the location for this course.


Are you constantly mixing MUD instead of the colours you want?


Have you ever mixed a great colour that felt accidental? And then you had no idea how to recreate it...

Are you wasting expensive paint and washing money down the drain?

Do your paintings look unsophisticated because you use paint straight out of the tube and boring obvious colours?


Simone Desilet's colour chart for Class 3: Yellow Day of Franz Marc's painting.


Ever wondered if there's some secret to colour mixing that no one has told you?

Do you repeat the same colour palette on every painting because you're intimidated by your paints or scared to experiment with new colours?

Have you been frustrated by a previous colour "theory" course with zero practical value?

Or does your career in film/theatre/interior design require you to have a nuanced understanding of colour?


If you answered yes to most of these. You're in the right place.

"I would say, if you want to really understand colour mixing and want a deep structure and understanding take the course."

- Alison Fleming



Careful! This is a crime scene!

There's been a murder and it's YOUR PAINTING!

Sometimes painting can be more dangerous than Midsummer County. Sadly bad things happen to good paintings. You were working away and then suddenly it all turned into an awful mess. What happened? Who's the villain of this story? Well in my experience it's almost always the obvious person - MUD!

But you're about to lay down the law when you become...
The Colour Mixing Detective.


Ok, let's solve this mystery.

Welcome to your first case Sargent! We have an investigation to get to so it's time to put those little gray cells to work. It doesn't matter if your paintings are realistic or abstract, landscapes or portraits every one who paints needs to know how to properly mix their colours. Mixing beautiful sophisticated colours will take your paintings to a whole new level.

Learning colour mixing is like doing scales on a piano. It’s not the creative part like performing the song in a concert, but it’s all part of the process of learning and practice. What most people do is avoid ever addressing this problem. They don’t want to do the work.

To understand paint you need to understand it's nature.

I want colour mixing to become effortless for you so you don’t have to waste any more time worrying about that stuff. It's time to end the frustration. This is a course you do once and then never have to think about how to mix your colours again. This is a totally learnable skill. You'll gain a deep understanding and then be free to pursue the real work of finding your artistic vision.

Making art is about so much more than mixing colours.



This is the course I would love to have had as a student.

It's one of a kind and far better than anything I learned in my 6 years in art school regarding colour mixing.

I can totally relate to your frustration with colour mixing. The problem isn’t you. It’s the way colour mixing is taught. Oh pardon me, I should say ISN’T taught. I had the same feelings when I was a student. I got around this by doing every colour mixing exercise in multiple books. Luckily for you I’ve created a course that doesn’t require you to spend this ridiculous amount of energy. In fact doing the prep for this course has significantly improved my colour mixing.

There comes a point in your artistic practice where you have to just do the work that needs to be done. Consider this course as a chance to learn what you need so you can finally move forward in your work.

It's time to take yourself seriously as an artist.


"I have a much better idea now of how to mix the colours I want, I am less afraid to experiment with colour and I have a greater appreciation for neutrals and their value in making non-neutrals "pop" in a painting." - Catherine Turl


My other course The Colour Match Maker is all about achieving harmonious colour relationships. Like a Jane Austen novel, you’ll be scheming to find the perfect match. In The Colour Match Maker we'll be working on real paintings. It's kind of like dating. We'll be trying out different colour schemes in your work and seeing what works for you. I want to give you a deep understanding of colour relationships so you can solve the problems that come up in your paintings.

Class 6: Here's Simone Diselet's chart from Purple Day.


Here's How the Class Works

I created Art School Untangled to teach one of a kind courses that you can't find anywhere else. These courses get right to the heart of problems students face and focus intensely on a single issue.



LINE UP CHARTS: You’ll see best results in class if you complete some of the Line Up Charts that I assign each week. These are charts I designed which allow you to see a huge range of colour mixes on one page. Before the Blue class if you complete the Blue Line Ups you’ll be ahead of the game as you’ll already be familiar with the colours. Working on this at home is the best option because you can go at your own pace. Students have described doing these as like a mindfullness meditation. Seriously, get ready to mix a ton of colour charts! I will give you detailed lists of charts to do and you can complete as many as you can.


In Class Work

DEMONSTRATION: You'll be in a small class of 7 people max. When you arrive you’ll choose an image from around twenty art history images which relate to our weekly colour theme such as Blue, Red etc. I begin with a demonstration where I show the nature of each colour group. We'll discuss the differences as group and try to figure out how to talk about them. It's quite challenging as we don't have the vocabulary to describe this kind of nuance.

ART HISTORY FORENSICS: Your class work will involve creating a chart where you try to mix all the colours you see in the painting. Most will be the weekly theme colour but not all of them. This will give you lots of experience trying to mix all sorts of different colours. Essentially you fixate on every nuance of the colour. We'll keep detailed notes on the mixes. Throughout the class I move around the room helping you individually and giving tips on how to go about mixing those colours with personal demonstrations. Students have described this course as like CSI. Kind of like doing an autopsy of a painting.


Weekly Colour Themes

Week 1: Blues
Week 2: Reds
Week 3: Yellows
Week 4: Oranges
Week 5: Greens
Week 6: Purples
Week 7: Earth Tones
Week 8: Coloured Greys


Class 3: Ingrid Anderson's chart from Yellow Day.

Change your perception as you learn from the great artists of art history.

You'll start seeing how beautiful and sophisticated the colours are in famous paintings. Matching the colours in art history images can become quite captivating. Students get obsessed with the nuance of colours. You'll be mixing colours you've never thought of. You'll be training your eyes to see a huge level of nuance. Students have described suddenly seeing colour everywhere they go differently. You might find yourself walking around Toronto trying to decipher how to make that colour out on the street!

You'll build a life long reference guide. When you're finished you'll pull them all together into a beautiful portfolio you can refer to for years to come. When I was a student I created a colour book and I've kept it for 16 years. I love looking at it!

The emphasis won't be on theories of colour but rather on the practical task of how to actually mix pigments properly. Sometimes the results are surprising and unpredictable.

Let's be clear - this course requires discipline. It's a lot of work.

You need to arrive with the right mindset. It is not about doing creative paintings and expressing yourself. This is about doing the hard stuff that most people never bother to do. You'll be taking your paintings to the next level.


"During the abstract painting class Gareth brought in his colour mixing book. It was and is very intriguing and beautiful. What got me excited was the process involved in creating a book like that. And the fact that I wanted to learn about colours & how to make colours." - Romana Huq


Class 3: Here's Ingrid Anderson's chart from Red Day

Shyamala Millar's colour chart for Class 6: Purple Day. Later in the course when she had more confidence she started to immitate the effects in this painting by Varley. This took the chart to a whole other level.

Course FAQ

I did a previous Colour Theory course and it was boring and repetitive. If I have to do another colour wheel I'll scream. I still don't know how to mix colours. How will this be any different?

No colour wheels. The Colour Mixing Detective is completely different from regular colour theory courses. I don't care about theories at all. They're irrelevant for mixing actual pigments. I created it based on what I think is essential to learn to understand colour mixing based on 17 years of painting experience. I'd say don't worry about that previous course. Consider it your intro to theories and this one as the practical side. I would honestly say that the majority of students have ended up obsessed with colours after a few weeks of the course. Fixating on an art history image and really going into depth on how that historic artist made those colours can be captivating. It's intensive and focused work but very rewarding.


"The class was hands on, not theoretical colour theory. I did that course before somewhere else. Learned nothing in the other class - learned tons with you." - Mary Ann Grainger


I'm worried this might be too hard for me. Will I be able to do it?

I've now taught this course to nearly 60 students of very different levels in this course and everyone was able to get it. The first two classes might be challenging at first. It gets much easier and faster by the time you get to class three. By the last three classes most students are pretty casual about it.


This sounds like a lot of work, I’m a little intimidated…

My classes are for real and designed to master the subject matter. They’re one of kind and intensive. You’ll have lots of time in class for the excercises but you'll need to do some homework.


I'm a total beginnner. Is this appropriate for me if I'm new to painting?

Beginners can do this course. Students with no experience have often done almost as well as those with lots of experience. The advantange of doing it right away when you're new is learning things right from day one. You don't need to undo things.


How does doing these charts help me to mix colours in my own paintings?

By studying the work of famous artists you'll see how sophisticated their colour is. You'll learn to be able to match the colours so that when the time comes with your own paintings you'll be able to recreate that colour you came up with. You'll learn the subtle variations that make all the difference in creating beautiful nuanced colours instead of obvious straight out of the tube colours. You'll also be exposed to colour palettes that are different from your own inclinations. This will help you to open up to using colours that might not feel natural to you but will enhance your range.


I work in the film/theatre/interior design industry would this class work for my professional career?

Absolutely. The course is geared towards fine art painters but I've had a number of students go through who have worked in set painting, makeup design and interior design. They've found it very helpful and applicable to their careers. It's all about gaining awareness and understanding of colour and that knowledge applies to industrial paints or makeup in your actual job. Send me an email if you have questions about whether the course would work for you and we can talk about it. In class you'll need to use artist materials so feel free to contact me about what medium would work best for you.


I'm trying to decide between doing The Colour Mixing Detective and your other colour course The Colour Match Maker. Which one should I do first?

In The Detective we go into great depth on mixing colours. By mixing them you start to see the full range of colours. They are two very different but totally complimentary courses. I'd suggest reading through both info pages fully in order to make your decision. In Spring 2018 this course is offered on Monday evenings which only happens once a year. Generally, I'd say if you're new to painting then doing the The Detective first is better. If you have some experience then either would be fine.


I need to miss the first class, can I still take the course?

You can't miss the first class. Missing the first class will make it impossible to follow. However we could make an arrangement.  If you are able to make the first class on the other day that would work. Or we could arrange some time before class 2 to do a private lesson in my studio where I teach you the lesson.


Is the class wheel chair accessible?

Yes. I’ve had a student in a wheelchair take the course. There’s a wheelchair ramp straight to the basement on the side of the building near Peter Street. There’s a ramp near the main entrance near Spadina Ave and an elevator on the main floor. Unfortunetly, the wheelchair accessible bathroom is on the 4th floor. The elevator is close to my studio.

Materials FAQ

I'm unsure about this course because of the cost of materials. Do we really need all these colours?

I totally understand the concern about the cost of materials. Trust me I have the same experience every time I go to the art supply store! Making art in not cheap. I've taught this to nearly 60 students and I've refined the course material list to the essentials. You won't regret buying any of these colours. They will be the foundation of your colour palette from this point forward. I've selected colours that allow you to mix nearly every colour you'll encounter.

It's impossible to mix every colour using blue, red and yellow or even a six colour system. That's way too simplistic. The problems most students have is previous teachers telling them that they only need a few colours to do their paintings. This is not true and leads to a lot of frustration. That being said, you also don't need millions of colours. This list is the essentials in my opinion. I promise you that you will waste considerably less paint in the future after taking this course.


Can I leave things at your studio?

Yes, you can leave all your supplies and paper at my studio. However there is homework so you'll need your paints.


What brands of paint should I use?

Below I list brands and the full material requirements. I think you should always use artist quality paints from day one. One of the biggest issues students have with painting is using crappy student paints. By starting with professional paints you learn to paint once rather than having to learn twice when you end up switching. Good paint makes good paintings.


What medium should I use?

Acrylic: Most students work in acrylic as it's easy and dries fast. But if you plan to work in another medium for your paintings then use that medium.

Oil: Working in oil is fine. You just can't use solvents in the studio. They're not necessary. Water mixable oils are also fine.

Watercolour: It's fine to use watercolour as long as you're committed to it as your medium of choice. Keep in mind that watercolour is very challenging. If you're just looking for a medium to use then I'd go with acrylic. If you intend to use watercolour then I have a separate paint list for you. I also have separate images that are watercolours to work from. Be sure to let me know if you intend to work in watercolour.

About Me

My name is Gareth Bate and I’m a full time artist, curator and art teacher living in Toronto. I work in painting, installation and photography. I have an email newsletter called "Art Untangled" where I talk about art every week. You can subscribe here. I've been asked if everything I do revolves around art and the answer is pretty much yes!

I've travelled extensively and visited all the major museums in London, Paris, New York, Washington DC, Boston, Montreal and Cape Town. I'm Festival Curator of the World of Threads Festival an international festival of contemporary fibre and textile art in Oakville. I graduated with a BFA from OCAD University and a diploma from Central Tech's adult art program. I've been teaching since 2008. I’ve been featured on CBC News and Radio Canada and in the Globe and Mail, Toronto Star, Now Magazine and La Presse among others.

Here are the courses I teach:
Art World Untangled: Museum Tours
Art History: The Masters: 1400-1850
Art History: The Moderns: 1850-1980
Abstract Painting
Outdoor Abstract City Drawing
The Colour Mixing Detective

Essential Class Materials

Art Supplies are not included in the course fee.

    3 large pads of WHITE watercolour or mixed media paper. Get ones where you can easily turn the pages rather than a block.

    A variety of flat square paint brushes.

    Palette knife (at least one)

    Pencil, Pen and Ruler

    4 or more water containers. (clean yogurt tubs or dollar store plastic glasses)

    1 medium to large flat palette of some sort. Don't buy a watercolour palette with different sections. Honestly the disposable sheet ones are great for this. There are palette's that use a sponge and can be sealed. These are great for keeping you acrylic paints wet. If you want to save money just get something in plastic like a tray.

    Latex or rubber gloves. It's a good idea not to get paint on your skin.

    A rag or cloth to wipe your brushes on.

    1 Scrapbook. You don't need this until later. So wait to buy this.


    Paint Colours:

    It's crucial for all students to have EXACTLY ALL these specific colours in regular paint tubes ready for the first class. I'll send you pdfs with the pigment codes for each brand of paint. Match the pigment code that appears on the tube. You'll need access to every one of these colours each week. It might seem like a lot of colours but after teaching this course six times I've found that this colour palette allows you to mix almost every colour that appears in art history images.


    I recommend you purchase artist quality brands. I believe it's important to learn to paint with artist quality brands right from the start. You should ideally stick to the same brand. Above Ground Art Supplies will give you a student discount if you show them the invoice for this course.

    Hues: If the tube says "Cobalt Blue Hue" on it that means the colour is not the actual pigment. It's a cheaper alternative version. Try to find the actual one if possible.

    Artist Quality Acrylics: Golden, TriArt, Windsor & Newton, Liquitex.

    Artist Quality Oils: Gamblin, Grumbacher, Old Holland, Windsor & Newton.

    Cobalt Blue

    Cerulean Blue or Cerulean Blue Chromium
