How come ashes turn white if I get them on black pants, but if I get them on my white pants they show as black?

Question

Example, yesterday I wore black pants and was smoking a blunt, and when I got ashes on my pants ,I rubbed them in, and there was a long white streak on my pants. My friend had a white shirt on and he got ashes on his shirt and when he did the same thing it showed as black. Why is that?

Ashes arent black or white. They’re both. You cant see the black ash particles on your black pants and cant see white ash particles on your white shirt.
