Have you got a Nerf blaster?
You can use it to help you learn French.
Write the colours (in French) on little pieces of paper, or cut out the words below. Stick these to a door or wall using blu-tack, or lay them on the floor.
Ask someone to shout out a colour in English, you must then use your blaster to shoot the French translation of the word.
For example,
"Red!"
"Rouge!" BLAST!!!
