i bought one of those shirts in the bahamas. It was a Bob marley shirt that would turn rasta colours when it hit the sun. Heat didn't affect it, like hypercolour shirts which used thermochromatic dye. The parts that turn colour are rough after a few washings, the shirt will only turn red and yellow in the sun. BTW, its only the parts with the hard white material that turns colour, the shirt itself does not.

Sounds similar to glow in the dark ink, where the sun actually charges the ink, and changes its color. Was the shirt you bought a white color t-shirt or dark colored, becuase it seems like that site I linked to above only sells light colored shirts. I wonder why that would matter.

the shirt I bought was white. I only saw white tshirts in the store. If they did black shirts I'd imagine the part that turns colour would look all crusty white at night..

Anyone know who sells hypercolour shirt(which used thermochromatic dye) blanks? I would be interested in printing on these, I loved them as a kid!

We have printed with the ink to see how it works, it is real cool only comes out in the sun. We bought some around 3 years ago and I believe back then it was about $180.00 per quart. We are working on our own line of tropical shirts and are planning on looking at using it. Yes it only works on white shirts. We experimented on other light color of shirts but it didn't work.

Body Faders provides both wholesale and retail pricing for thermochromic garments and fabrics. They are releasing a new line of Super Reacto shirts that react even faster than there regular ones. There is only one thermochromic manufacturer and it is Body Faders. You could ask WalMart to make you some but then there goes another 3 million jobs in the US.

For all your information Body Faders thermochromic effects can be washed as many times as you want in regular washing machines at any temperature with any detergent as long as there are no bleaches. I have a t-shirt that I have washed at least 30 times with jeans in hot and cold water with no problems.

I have opened a new company called Technacolourtees that now has a new formula that is 100% washable in all detergents and machines. New items are tshirts that are 3 times deeper in color and still hold washing perfectly with our new formula called HYPERFIX.

We created the dyes and formula. I am the person who revived the hypercolor technologies in the 2000s. I sampled for American Apparel and one month later they poached the idea. All other shirts you see on the market where made by my companies.
