That said, my own opinion is that coloring hair is much like wearing makeup or dressing nicely and wearing jewelry, etc. I think it's alright if it's done tastefully and doesn't become an obsession. (Obviously I'm talking about women wearing makeup -- I wouldn't advocate men wearing eye shadow that was "tastefully" applied!) I even think that wild colors on younger woman are not necessarily sinful, but I am horrified when I see an older woman trying to pull it off.
