I buy the Crayola brand watercolor set in a box at walmart for around $4.00. I think you get 10 colors. You can buy these in larger bottles at the craft stores too. It is not runny so it stays put on the plate without running into the other colors, it’s a good consistency. I love this paint – the colors are very vibrant.
Clean up is a breeze – throw away the plate palette, rinse out the brushes and wipe off the table. This paint comes out of carpet, clothes and hair with warm water very easily.
My youngest learned not to mix the colors or else she would end up with brown or black and she loves the colors so this is not an issue anymore. She learned this after only a couple of times of having to paint with an icky brownish color. lol She was barely 2 at the time.
