Sabrina Abu-Obeid, a musician in Florida, dyed her hair. What color is it now? That depends entirely what room of her home that she's in. As the lighting conditions change, her hair appears to be either purple, violet, or pink. It's like she's wearing that famous white and gold dress on her head!
Abu-Obeid and her boyfriend--the deeply impressed man holding the camera--make up the band TeraBrite. You can see their music videos on their YouTube channel.

I have a piece of neodymium glass on my desk that will be bright pinkish-purple in sunlight and one type of fluorescent lighting, and a grey-blue in other fluorescent lighting, and about any color in between with multiple light sources.
