Colour mixing with food colouring and water

Modified: Sep 12, 2022 · Published: Mar 29, 2017 by Emma Vanstone · This post may contain affiliate links · 4 Comments

Colour mixing is a great activity for learning about primary and secondary colours as well as fantastic fine motor control practice if children use a dropper or pipette. Once children have made secondary colours they could then experiment by mixing primary and secondary colours to make tertiary colours or try to make as many different shades of one colour as they can.

Materials

Plastic plates

Water

Beakers

Food colouring

Pipettes or droppers

Instructions

Add a small amount of red, yellow and blue food colouring to separate beakers and then top up with a little water.

Use the pipettes or droppers to drop different colours of water onto a plastic plate and record which new colours are created.

Colour Mixing

What is a primary colour?

Primary colours cannot be created by mixing other colours together. These are:

Red, Yellow and Blue

What is a secondary colour?

Secondary colours are made by mixing primary colours.

Yellow + Blue = Green

Red + Yellow = Orange

Blue + Red = Purple

What is a tertiary colour?

Tertiary colours are made by mixing a primary colour with a secondary colour.

Questions to ask about primary colours

What do you think would happen if you used a paper plate instead of a plastic plate?

Do you think the colours would still mix if you used filter paper or kitchen roll?

Which colours do you think are warm and which cold colours?
