Free interactive colour tool
Hi, I’m Richard Robinson. The Gamut Mask is the simplest way I know to choose colours that always work together — no more muddy palettes or guesswork. Play with my free tool below, then I’ll show you how to really make it sing.
Have a play
Drag the wheel to rotate it, pick a mask shape, and watch a perfectly harmonious palette appear. It’s free, and it’s yours to use as often as you like.
Drag the outer edge of the colour wheel to rotate it and tap a mask shape to see your palette — works on phone, tablet or desktop.
Loved the tool? Let’s find the perfect painting to practise colour on.

See it in action
First I designed an image with a limited value study. Then I decided my most powerful colour would be the orange in the foreground, and I made a triangular mask with yellow-orange as the dominant colour, supported by a greyed red and a greyed green.
Then I removed every other colour from my palette so I wouldn’t be tempted to dip into them — and painted the first little study. Satisfied with that, I made two more. Each painting is harmonious, yet each has its own mood. That’s the magic of the gamut mask: it makes “colours that go together” almost automatic.

Here’s how I use the gamut mask to plan a harmonious palette before I even pick up a brush.

“Mastering Color covers all of the main points with clarity and straight talk. It’s practical and down to earth and easy to understand. The mind boggles when I think of how many painters can use this.”
