Yes it's called electrochromic glass, although it's actually more kind of glass laminate. But yeah it can be engineered in such a way as to change color depending on solar output or on the presents or absence of an electrical impulse. It's been around for about 20 years but it's only been practical for about 10.
People have even already integrated it with transparent displays so all of the technology is already there. It just needs commercializing.
Polestar apparently have a car with electrochromic glass in its windows so you can turn those into a computer display.
