Love it, I think blue will be my next colour when I need a change from purple.
Going between blue, green, and purple is my favorite. The change is enough that I don't feel bored and the colors go over each other well.
Oooh keep the ideas coming I like this. My fringe faded after three washes to lilac streaky bits (which was nice) but when I next washed it I blue conditionered the crap out of it and so far so good it's all blue again π
Coloured hair is fun.
