as for stand out hair color, I can relate, I spent part of my summer in So Cal with my Bestest Friend from Freshman year and she had these AWESOME punk rocker red streaks in her hair AKA bitch streaks as we refered to them the whole time i was there I loved them, the day before I flew home I got the same thing done, I had ULTRA blonde hair and when I got home it had red, eggplant, pink, and blonde and dark brown in it!!!!! No one expected me to do this so it was a shock, ( IE my parents and my ex about fell out of their chairs when they saw me) but it is HAIR you are changing your appearnce NOT YOU !!!!
JUST remeber that and you will be ok
best of luck !!!
