from a hairstylists brain here.
in my opinion i think blond would have suited you. were you planning to do it yourself? or get it done professionally? as far as the black hair...boy have i learned my lesson with that. it took me a year to get it out of my hair a few years back. i did it gradually. i didnt want to fry my hair and cause alot of breakage etc...are you wanting to go all over with the blue? or just some chunky highlights? blue colors would be kool. adding peekaboos would change it a bit.
