True Red/orange with trimmed carpet to match very light complextion.

The darker the better.

I tend to seek out the brunettes because my favorite hair color is one that is hard to find.

A lady with shiny, long, black hair and a narrow strip of matching black pubic hair drives me absolutely insane.

Jet black with pale skin, green eyes, and a mildly goth presentation.....

is one of my favorite combinations (and describes one of my favorite ladies....)

Light brunette / dirty blonde if the hair is natural and luxurious, not dried out with improper treatment or coloration.

Blonde if the lady looks like she should be a blonde and if there again the hair looks and feals natural and not over processed.

Not to leave the reds out, I love strawberry blonde to light red hair that is natural. Let me have a spray of freckles with it as well. However the harsh brassy red artificial colors that seem to be in vogue do not appeal to me.

In any case I love a bit of a landing strip to match. Or even a trimmed natural presentation.

Call me old fashioned '

if the color of her hair matches her complexion. A hair color that doesn't fit her complexion is a big turn off.

There's a great question

I love girls with black hair and bright red highlights but would have to go with anything out of the norm. Pink, Blue, Red, those old school silver wigs. You know, anything that stands out of the usual.

I like a hair color with subtle highlights that tasteful and not too far off from the natural color.
It's worth the investment to get your hair done by a person who get the color style that looks the best for you.
Also clothing the goes well with color is important.
