Mix a New Colour: illustration of a toddler doing the activity

Mix a New Colour

from 30 months · 30-40 min · Fine motor

What you need

  • two pots of paint, blue and yellow (then red and yellow)
  • a sheet of paper
  • an old shirt or apron

How to do it

  1. Put a blob of blue and a blob of yellow on the paper, side by side.
  2. Ask what colour they think will appear if the two blobs meet.
  3. Let them swirl the blobs together with a finger or brush and watch green appear.
  4. Try red and yellow next, then let them paint with the new colours.

Why it matters

Watching two colours turn into a third is a small bit of magic they made happen with their own finger.

What they're learning

Colour names
Blue, yellow and the new green all get named as they appear.
Guessing then checking
Saying what might happen, then seeing what does, is how finding out works.
Finger control
Swirling just where the blobs meet takes a steady finger.

What to look for

Notice them trying it again on their own with a different pair of colours.

A tip

Use only the two colours you're mixing so the green stays green. Washable children's paint wipes off hands and tables.

Make it easier or harder

Easier: just one pair, blue and yellow, and lots of swirling

Harder: add a dab of white to make a colour lighter, or ask them to make the green 'more blue'
