Do guys prefer blondes, brunettes, red-heads, or girls with jet-black hair?

It doesn't really matter, all colors are beautiful and it depends pretty much on the girl. Personally, I love light eyes with dark hair and blonde, ginger hair with dark eyes. Examples of such girls are Megan Fox, Marie Avgeropoulos, Kat Dennings, Rita Ora, Shakira.

Yes! I like them all. Blondes are beautiful, brunettes are wonderful, red heads are amazing, and jet-black is just awesome.

i prefer the color my wife has now red hair

for me, any but black.

Black is the basic color for normal people. Other colors are different because perhaps it's some type of exposure.

Me personally, yeah all but black. sorry ladies :P

blondes
