Personally I'm leaning towards the Midnight Blue or Blue Mayhem, as those are darker or closer to blue (respectively) than the rest.
PS: I intend to 'dye' my hair without actually bleaching it first. I want the 'highlights' look they advise will happen if you dye dark hair.
Which shade of blue would you recommend?
Do you have an alternate source for blue hair dyes?
Would you like me to post nudes after... nah, I'm just kidding.
