Unfortunately, "different" types of self adornment seem to be much more accetable if you're young. *sigh* I dyed my hair purple a couple of years ago, and all hell broke loose. Parents pulled their small children out of my path; fellow musicians whispered behind hands; folks freaked out over a temporary hair color. Those with permanent makings caught less flack than I.
Sad thing is, I loved my purple hair. It made me feel giddy to see it in the mirror, and I felt very young and exciting.
Blessings on you if you do what you want with personal decoration, be it piercings, tattoes, of hair color. Purple hair made my public life a living hell, and when I complaine dabout it, a friend said, "You knew what you were getting in to."
Life's too short, do what you want. I just have to be a platinum blonde now.
