Colour is everywhere, once you go looking.
Grandpa Wise says
You don't need a craft cupboard or a plan. A single question — 'can you find me something red?' — can turn your whole home into a game for twenty minutes.
The Colour Hunt
Name a colour and send them off to bring back something that matches. Line the finds up on the table like a little rainbow. Then let them choose the next colour and send YOU hunting — being the one who gives the orders is half the fun.
Why it works: Colour names, memory, and happy independent scurrying.
