Alphabet stamping

We have been trying to figure out all possible ways of making use of colours while trying different media to paint as well.

Materials needed: paints, plastic ABCs

This time, I asked A to mix two colours to form a third one and now she knows, when blue colour mixes with yellow it gives green colour.
The green colour seen in pics, is not the one we actually used for painting. A mixed yellow and blue colours that has turned green.
