Hi, I've designed a roller piece. I've got everything I need to actually make it, except paint. I found some cheap bucket of white paint, however, I need two contrasting colors (preferably black and white). This paint that I found is only available in white, so is there any strong dye I can add to the paint so I can make it a dark color?

I was actually thinking of opening a black printer cartridge to use as pigment, but maybe there are better alternatives :]

Anyway, I you have any idea on how to color white paint, please comment ✌️
