I'm blonde

But I don't know what shade it is... well here's a picture anyway
^ Then that's it too... IDK Why it looks too different shades... maybe the lighting?? (Well I was outside for the second one, then in my closet for the one before, so that probably has something to do with it...)
What do you all think about about hair length on blondes? My friends say only brunettes look good with long hair (but they are brunettes, soo...)
Mine is a few inches past my shoulders and I (had) bangs, but now they are pretty long and almost touch my chin.
What are some good styles that look pretty with blonde hair?
Thanks!
