Colour Mixing for Beginners: The Colour Wheel Made Simple

Knowing how colours work saves paint, money and frustration. With just a few tubes you can mix hundreds of colours. This guide explains colour mixing using the colour wheel: primary, secondary and complementary colours, warm and cool colours, tints and shades, and practical recipes for greens, browns and skin tones. It works for acrylic, watercolour, gouache and oil paint.
The colour wheel
- Primary colours: red, yellow and blue. In traditional painting, these are the colours you mix others from.
- Secondary colours: mix two primaries. Red + yellow = orange, yellow + blue = green, blue + red = purple.
- Tertiary colours: mix a primary with a neighbouring secondary, such as yellow-green or red-orange.
- Complementary colours: opposite each other on the wheel: red and green, blue and orange, yellow and purple. Side by side they look vivid; mixed together they make greys and browns.
Why some mixes turn muddy
Every paint colour leans slightly warm or cool. A blue that leans towards green (such as phthalo blue) and a yellow that leans towards green (such as lemon yellow) make a bright green. A blue that leans towards purple (such as ultramarine) mixed with a warm yellow makes a duller, olive green, because each one contains a little of the third primary. For the cleanest purples, try magenta with blue rather than an orange-red.
Warm and cool colours
- Warm: reds, oranges and yellows feel sunny and seem to come forward.
- Cool: blues, greens and purples feel calm and seem to move back.
- Use warm colours in the foreground and cooler, lighter colours in the distance to add depth to landscapes.
Tints, shades and tones
- Tint: a colour plus white, lighter and softer.
- Shade: a colour plus a little black or a dark complementary colour, darker and deeper.
- Tone: a colour plus grey, more muted.
Add dark colours to light ones a tiny bit at a time. A drop of blue changes a lot of white, but white hardly changes blue.
Useful colour recipes
- Bright green: lemon yellow + phthalo blue.
- Natural greens: add a touch of red or brown to tone down bright green.
- Brown: mix complementaries, such as orange + blue or red + green.
- Skin tones: start with white plus a little yellow ochre and red, then adjust with a touch of blue or brown for shadows.
- Rich black: dark blue + dark brown, often livelier than tube black.

A colour mixing exercise
- Paint a circle divided into 12 sections.

- Fill the six gaps with tertiary colours.
- Below the wheel, paint a row showing each primary with more and more white added.
Frequently asked questions
How many colours do I need to start?
A warm and cool version of red, yellow and blue, plus white, will mix almost everything.
Why does my purple look brown?
The red probably leans towards orange. Use magenta or crimson with blue instead.
Should I use black to darken colours?
Use it sparingly. Darkening with a complementary or a darker colour often looks more natural.
