Kids Design Room

What colors or design should I use to paint a daycare room?
I run a daycare from my home, and we are building a new room just for the daycare. What color should I paint the room? I have a light gray flooring. I want the room to be fun for the kids. I need some good ideas for a creative childcare space. Should I paint the ceiling, too?
don’t paint the ceiling because it should be the focul point if its white and everything else is coloured(you have to keep the balance)
If its for kindergarten, i suggest(i kno wits alot of work but onc eyou have the end product it’ll all be worth it) you do one wall of sailboats. Not little ones, a few large ones(bigger than the kids) and water there. on another sie you could do like a forest and another of maybe like different coloured crayons lined up vertically. If these are too much work, I would suggest doing the elements(earth, wind, fire, etc.)
