Why is it that when I use a black Sharpie to hide a tiny bleach spot on a pair of black cotton pants, I have to reapply the marker after every washing because the Sharpie marker always washes out?

But then when I get a tiny little bit of black Sharpie marker on my pink cotton t-shirt it won't come out no matter how many times or how many ways I wash it?!?!
