rainbow (i know a girl that did and it looked awesome!)
or blue with diffrent shades
A few shades warmer than it is now. It'd offset how pale you are.
Why dye your hair at all? Work with what you've got. At least you HAVE hair... ;-)
unless you are covering grey, leave it natural
Keep it natural it's more cuter :) , or if you usually die your hair , dye it kind of brown and blond :)
