I really like [img]https://dl.dropboxusercontent.com/u/54123195/RoyalPurple.png[/img] or at least purple around that shade, and purple in general, especially when combined with black.

([URL=http://syrsa.deviantart.com/gallery/]Syrsa (NSFW)[/url] is a good example because he tends to use a lot of colors in that range that I really like, even if you think his art is questionable.)
Hex value #566F70
