It's turning out to be more of a logo/avatar, and not a symbol...
Symbol (n):
# A printed or written sign used to represent an operation, element, quantity, quality, or relation, as in mathematics or music.

So the *&^%$#@! are all symbols, and pictures with colours are not, a silhouette is more of a symbol than those, the colouring would then be right...

i dont want avatar... symbol or logo
