What color of clothing should I wear to minimize the amount of UV rays penetrating to my skin?

Yes, I know that you get hotter in black clothing, and stay cooler in white clothing, but I'm wondering only about UV rays.

??????????

long sleves in light colors the uv rays may still get thru but not as much as they would if you were wearing dark short sleves its fact lame but true.

I don't think the color really matters, but the fabric can't be too thin. it has to be strong sturdy fabric
