Possible Light Summer hair. Often, the hair is lighter as children and lightens a lot in summertime, but won't darken much beyond these colours in maturity. The big swings from very light to very dark are usually Winters.
Wish I knew how to style my hair like this. Correction: I know how to style it like this, but don't know how to get my uber-fine hair to HOLD the style. Have had too many failed attempts, and now I don't bother.
