You may want to try doing a medium blonde with of course highlights and lowlights, since most blonde hair isn't a flat blonde(with the exception of some fairer ethnicities i.e. Swedish, etc.)I have a friend who is naturally a dirty blonde, but instead of dying her hair a lighter blonde, she has her hair highlighted and what not instead (salon, not at-home coloring). It looks so much more natural and healthy than just dying all of her hair blonde. She's around an NC30/35 at the moment(sun tanned, not spray/bed), and it looks just as natural as when she is fairer. It may help if you stated your eye color, natural and/or current hair color, and hair texture. HTH!
