Burnette in real life. I like every color in anime
I don't hate any colors per se but I do have a preference for red hair and long black hair.
I don't really know, i've met people with awesome color dyes and others... well, not so much.
IRL: Blue, Purple. 3DPD: Anything, as long as it looks good.
Dark hair is good.
I have really dark brown hair and I quite like that colour. I've been tempted since I was a kid though to dye it Blond for a little while and see how it looks, but not sure if it would look okay on me or if it'd damage my hair, plus I'd want to go back to my original colour at one point and I'm not sure it would be quite the same, hence I've never done it.
If we talking about 3DPD, blonde is best, followed by black. I dislike blonde dyed hairs, tho. (and most dyed hairs in general).
Now if we're talking about the world that matters, anything goes. Besides red. Red sucks.
blacks are pretty cute but blonde hair will suffice in a pinch
