This color changing tee changes colors in the sun! Two colors in one. Using Spectrachrome technology, Del Sol clothing burst into colors using the power of sunlight.
Two different designs offered.
Our custom Sunspot Solar Observatory logo comes on a 100% cotton natural colored shirt. A dye-tied effect instantly appears when UV light is exposed to the shirt.
The other design features the Dunn Solar Telescope as a prism with a light stream entering and exiting the telescope. When UV light is exposed to the shirt, a rainbow of colors is projected. 100% cotton black tee.
Color change indicates the sun's UV-ray intensity. The more intense the color change, the more you should protect against sun exposure.
