Eli5: Why is it easier to darken white paint than it is to lighten dark paint?

Question

I remember in elementary school that I was mixing paints and to make grey, and I found that a small quantity of black darkens white super easily whereas even a 50-50 split of black and white leaves an almost black color. Is black paint more potent? Is there some kind of complicated color theory?

Answer 1

Adding pigment to paint is easy. Subtracting pigment from paint is not. You can only try to neutralize it.
