So What you need to start with these material's , you need a small container with a lid, a paint brush, food coloring,and a plastic fork or spoon.
Take your container and pit some water in it pretty much the whole thing. Then you choose your food coloring and put a few drops in; really however many drops you put in makes it how dark you want it. I suggest you use more because if it gets to light it will fade.
Use your spoon or fork and mix the color or colors that you put in.then take a piece of paper out and a paper napkin and out the paper on top of the napkin and test out your color!!!
