I'm guessing you're referring to the head of the penis? It would be because when the penis is erect, the blood vessel in the shaft swell to allow blood to rush in and keep it erect. The redness is merely a result of the blood going to the penis.
The glans penis, commonly called the bell end or knob end, can vary in colour from person to person, various shades of red and purple, dusky pink and pale bluish are all pretty common.
Yes red bell peppers come from green bell peppers, as do most bell peppers. They develop their color variances and flavor as they ripen. If you are growing bell peppers make sure you choose a variety you want, don't assume your green bell pepper will ripen into a lovely red as you may be disappointed and end up with a yellow or chocolate colored fruit. Variances are great and may vary immensely between (yellows, orange, reds, purple, and brown) Try growing the "Chianti Bell" It's a nice red bell pepper with a thick sweet hull. Yummmmmm :-)
