Motives for Paint Schemes

I like learning about airlines and that make paint scheme decisions for specific reasons. Like when Us Airways went with a white scheem because their planes would be in the West Coast heat. Or airline that go bare metal to reduce paint weight and reflect away heat.

Another one I like it S7 from Siberia, paint their planes bright green...



...so the planes are easily found if they crash in the white tundra.

Are there any other planes that do this? Or any other airlines with other motivations for designing their scheme beyond aesthetics?

I believe Concorde could only be white because it required special heat resistant paint. The blue Pepsi scheme was not allowed to fly faster than Mach 1, and even then only for a few minutes at a time or else the paint would melt.
