One of the biggest misconceptions about watercolour is that you need lots of paints to get started. Rows of tubes, endless colour names, and the pressure to buy “the right shade” can feel overwhelming - especially for beginners.
The good news?
You only need three colours to begin.
Red.
Yellow.
Blue.
These are known as your primary colours, and when you learn how to mix them, you unlock a whole world of colour — slowly, intentionally, and with far less pressure.
Why Start With Just Three Colours?
Starting with a limited palette is one of the most helpful things you can do as a beginner.
Here’s why:
-
It builds confidence quickly
-
It helps you understand colour, not just copy it
-
Your paintings feel more harmonious
-
It removes overwhelm and decision fatigue
-
It encourages play and experimentation
Instead of reaching for the “perfect” tube, you begin to trust your eye and your intuition
The Basics of Mixing Watercolour
Let’s break it down simply.
1. Red + Yellow = Orange
Adjust the balance to control the warmth:
-
More red → deeper, warmer orange
-
More yellow → soft, golden orange
2. Yellow + Blue = Green
This mix is incredibly versatile:
-
More yellow → fresh, spring greens
-
More blue → deeper, cooler greens
3. Blue + Red = Purple
Purples can be tricky, but also beautiful:
-
More blue → cooler, moody purples
-
More red → warmer, plum tones
By changing the ratio of paint to water, you’ll also get lighter, softer, or more intense versions of each colour.
No two mixes are ever exactly the same and that’s a good thing.
Why Mixed Colours Feel Softer and More Cohesive
When you mix your own colours, they naturally relate to each other because they all come from the same three pigments. This creates a sense of harmony across your painting.
You’ll notice:
-
Fewer harsh contrasts
-
Softer transitions between colours
-
A more relaxed, painterly feel
This is especially lovely for landscapes, travel sketches, florals, and everyday moments — the kinds of scenes that invite you to slow down and notice.
The Hidden Benefits of Colour Mixing
Beyond technique, colour mixing offers something deeper.
It helps you:
-
Slow down and stay present
-
Let go of perfection
-
Build patience and curiosity
-
Enjoy the process, not just the outcome
There’s something grounding about watching colours bloom together on the palette — it turns painting into a quiet, mindful moment rather than a task to get “right.”
If you’re new to watercolour, start here.
You don’t need every colour.
You don’t need fancy supplies.
You don’t need to know all the rules.
Begin with three colours.
Mix slowly.
Observe what happens.
And let yourself play.
Watercolour is as much about feeling as it is about technique — and colour mixing is one of the best places to begin.
