My brothers all had these. Neat idea.

You so could not wear these on a date or if you made out in the car in the driveway everyone knew when ya came in!

i had an orange one that changed to pink!

I had one in really cool like blue to purple. Damn..the weird stuff they came up with to sell. Those were the days when you could goof off and not be so serious.

I was born near the end of the eighties, but grew up admiring the hypercolor shirt my father had. Light purple on one side, pinkish on the other. It doesn't work anymore, but I still wear it. There's an American outfitter of some sort that has their own color changing shirts.

my daddy told me about these shirts:) i plan on bringing them back:) can't wait to get one!!! i just wish they werent so darn expensive!! my dad says that he had to wear them in pe so that the teachers could tell who was actually working and who wasnt:)

I had a T-shirt that changed from blue(when cool)to purple (when warm). My ex sister-in-law ruined it when she put it in the dryer. It was "stuck" with blue and purple areas, and wouln't change any more.

I found one just like the one my SIL ruined on Ebay. I bought it, and it works fine. I also have 2 others--purple that changes to blue, and a gray/aqua one. The aqua gets lighter and the gray turns yellow when warm. The only thing that saves these shirts is to hand wash in cold water, do not wring out, hang on a hanger and let drip dry. Do not dry in the dryer or outside on a clothesline in the sun.

I enjoyed that!

"Hypercolor" - I totally remember this! I had one that was a sweatshirt. I wonder how this fabric worked? So COOL! I remember holding my hands on the shirt to leave handprints.
