To Dip or Not to Dip?

Off topic here! Lately I have been wrestling with the idea of dying my hair a crazy fantasy color. The idea or dip dying my hair came to mind because well, simply put, if I don't like how it turns out I can always cut the ends off. 

Have you ever dip dyed your hair?
Were you happy with the results?
What color did you use?

 Some dip dying inspiration!

Pale Green Eyeshadow and Brown

Love this!
