what is the hottest hair color

I really like the color pink, it's not so dark like blue or black. It's a perfect combination of red and white.

Red, Blue, Orange and Green for clothes...
For hair, I prefer black.

White. So plain, clean, and simple.

Blurpl mix of blue and purple.

gotta be red, definitely

Black, Red, Deep Purple and Yellow.

I like deep and dark shades, especially red, blue and black. Anything pastel or neon (and any sort of yellow, really) is rather annoying to me.

My wardrobe has pretty much black clothes only, I don't even wear jeans. It has been a habit for almost ten years now, and people kind of expect it from me.

Red, blue, green, yeeessss!

Dark hues of blue tend to tickle my fancy.

Clothing? Usually black for me. Hair? Too many to name...

Oooo Red and Purple for a women and Dark Blue and Red for men, absolutely nothing brighter than red... cuz now we're talking turn-off.

Clothing: red, mainly because of it's link to sexuality (dear god I've been reading too many psychology text books.) or black because, let's face it, everyone looks good in black.
Hair: any, I'm not fussed.

Black,Red,Silver and Gray

green blue red/pink

Aqua and cream... they make the best combination

maybe black in clothes and in hair, but I really like violet clothing.

black & dark red..

Hmmm....In RL, I would say black hair has the biggest impact in my case with brunettes coming a close second. In the anime world, just seeing anbarry's avatar reminded me that I love orange hair as well, like Anaru's or Nami's from One Piece. Although, overall, I would still find black hair the most appealing IMO in either realm.

I'm shocked red is so popular. I love red headed girls, 2D and 3D.

Black due to the fact the color black absorbs heat energy from the sun. White would be the coldest hair color due to it's reflective properties.
