Would you be disappointed if ET colored his hair? I wouldn't. The teaching is about not identifying with forms. It's not about being against forms or not enjoying forms when they can bring you some kind of pleasure (just not getting attached to forms).
I'm not sure if I'm trying to defend myself? I do color my hair into a color that is different from my natural hair color because I just prefer that color for my hair for the time being like I prefer sunny blue sky to dark clouds or certain color for my clothes or something. I don't do much makeup not because there is anything wrong with it but just not my preference. Either way, I don't identify myself with my hair color or my face or my body...when I'm truly present or in the moment. I had this experience one day that I felt myself transparent and didn't feel others could see me or I simply didn't mind whatever others perceive me with my appearance and my past or future...
I would like to believe I could still enjoy beautiful things when I get enlightened
