Just wanted to add I believe colorism is like racism..it's unfortunately natural to most humans. Personally I don't think it'll completely end. It's human nature and I don't believe all humans evolve or will evolve past it. Certain societies/communities can systematically be less tolerant of it though.
Colorism also exists where my parents are from, Bangladesh. The lighter skinned/fairer women/girls are automatically more attractive even if they are ugly as ****. My family (parents generation) are very much into skin color.
