I would rather see the natural hair color, I don't see why people change their hair color to some other "natural" color. Your own natural color is perfectly fine, no matter what it is. Some people will love it and it won't be the favorite of some people, no matter what natural color you have or dye it.
I think the most important thing is to take good care of it in the first place, and dying it is not really good for it. If you're going to dye it, it just seems kind of pointless and boring to me to dye it the color of some other person's natural color.
If you're going to color it, you might as well go all out and get some real fun and interesting colors. Maybe blue, or purple! Although I know not everyone would appreciate that quite so much :P
