I don't really do purple on my eyes any more, I'm not happy with it. I used to as a teenager, and I do wear purple shades in clothes, nail polish and lipstick, just not eyes. I don't think it works well on blue eyes.
There's only one purple eyeshadow in my stash at the moment, and that's a Bourjois single in Violet Fascinant, a pretty colour but I don't use it. Bear in mind I use all the rest of my Bourjois singles regularly -- they do high-shimmer shades that are great to work with wet -- so it's definitely the colour rather than the formulation that's turning me off.
