darker genitals

I agree I like it when There is some skin tone difference. I especially like cocks that have a different colored head. Though I have to admit it would probably be a turn off if the color difference was so stark that it became a distraction but I've yet seen any that would be an issue.
 
Mine is darker than the tops of thighs and in line with the rest of me during summer. In winter with no sun, it seems to moreorless stay the same while the rest of me fades in colour. Weird.

I'm mixed race too.
 
I am of the Latino variety and have equipment that is colored quite differently than the rest of me. My balls are generally in the tan category, but when I am aroused, they darken considerably. For my cock, it depends on whether I am soft, aroused, or ready for action. My cock might be anywhere from light to very dark tan, purple almost. Makes for great drama when I erupt.
 
Mine is darker than the rest of me. Half German and half Hungarian, blue eyes, brown ash hair.
One time Dad told me that Mom asked him why his was darker than the rest of him, and he said that it was the gypsy in him.
It makes sense for it to be darker since the thin skin has more vessels close to surface, and very dense on soft penis.
