Orange. It's discusting. It is the ONLY COLOR other than red that has not been my 가장 좋아하는 color at one time. Anyone who likes 주황색, 오렌지 is colorblind, I think.
Gray. (And yet, 8theGreat's 가장 좋아하는 color... ._.) It just looks pretty ugly to me. White looks alright and black looks alright but gray, for some reason, just seems... eh.
