I am thinking of adding a mix of some turquoise/green/dark blue to my bangs, sort of like a peacock combo. My only issue is fading, as it really bothers me when the original colours have changed. I really like the look of peacock blue, but 2/3 reviews said it faded into a really ugly moldy colour. Fishbowl also looks pretty sweet, but people keep saying it fades fast, and it looks a little lighter than i'd really want. I think there was another one called Directions Turquoise, what does that look like faded? Basically, i'd like to get a collection of colours that won't look too horrible in it's dying stages.

If anyone needs to know, my hair is bleached light blond so all the colours SHOULD turn out how they're supposed to.

Peacock blue only goes a moldy colour if your hair wasn't bleached light enough in the first place. I've used it many times and for me it just becomes a lighter version of the original colour. All the colours you mentioned fade really nicely in my experience.

I have Directions Turquoise on my fringe right now. It's currently turquoise, but because parts of my hair were bleached to a somewhat yellow-ish blond it turns greenish as it fades. But I like the green that it's fading to, too. And it's lasting alright.

If you put any such colour on orange toned hair, that could be a problem I guess. But since your hair is light blond you shouldn't have a problem.

This sounds promising. Thanks a lot for the responses, guys!
