Dye a strip of the hair colour in to your hair, then if you like it go with the full head :)
The best way to know what color your hair is, is to look at it. If your hair has been colored, you can look at pictures of yourself before your hair was dyed.
green hair
Depends mostly on color of skin and the feeling of ur hair if ur hair is flat then you will look bad if it's straight but thick then it should look okay personally I think scene hair looks bad
green is always good with red hair
probably not, because it is an unusual hair color
brunet
Purple or electric blue.
gold or silver
it depends if your going for a scene look or emo look but it looks good on me and a lot of other people i know but it really depends on your facial structure and what kind of hair you have. Thin,thick or whatever if your hairs damaged from color. it all depends hope this helped. :)
navy blue
likes the color maybe? or it makes him look good!
be careful , if you put color on already colored blonde hair it could stain your hair.
