Hypercolor was a line of clothing, mainly T-shirts and shorts, that changed color with heat. They were manufactured by Generra Sportswear Company of Seattle. They contained a thermochromic (temperature sensitive) pigment that changed between two colors – one when cold, one when warm. The shirts were produced with several color change choices beginning in 1991. The effect could easily be permanently damaged, particularly when the clothing was washed in hotter than recommended water, ironed, bleached or tumble-dried. Between February and May 1991 they sold $50 million in Hypercolor garments. Generra went bankrupt due to mismanagement and fading demand in 1992.
I got into trouble w/ this shirt. My girlfriends mom came back early and found hand prints on it that were obviously too small to be mine. We tried to say we were just sitting on the couch watching a movie. I guess the guilty looks said otherwise. Damn you Hypercolor!
