T-shirt Color and Temperature Effects

The video explores how different T-shirt colors affect body heating from sun rays. Eight identical T-shirts of various colors were tested on mannequins to measure temperature changes. The experiment revealed that black and purple T-shirts heat up the most, while white and gray remain the coolest. Recommendations include wearing lighter colors in hot weather to stay cool.
