To get turquoise the standard dye to use seems to be SFX fishbowl:

I know it is a good colour and brand, lasts as well as can be expected of a blue, and is easily available. All in all, a good choice. But I was wondering if anyone's tried other turquoises and what results they got?

Specifically, these:

Crazy colour peacock blue:

Thanks guys :)

Yup I've tried both.
Peacock blue is quite dark and much greener than fishbowl. (http://haircrazy.info/tags/peacock/)

Turquoise is very similar to fishbowl and my current fav. More info: http://haircrazy.info/tags/turquoise/ - things tagged turquoise
