Jim Lee introduced one of Storm's most iconic looks in the X-Men reboot of the early 90s.
I read on a reddit thread years ago that Jim Lee had intended it to be a shiny black leather, but intention isn't the same as perception. As coloring techniques advanced, later artists depicted it as white, silver, gray, and black. Even her figures/toys show all different variations.
The question is, what color do you see it as?
