It's always been blue since I joined and was carried over from the VB version , To me it's a taz icon .
Talking about purple I'd a purple theme years ago because I wanted to avoid greens and blues ( a local issue)
There I was , quite happy with the choice until a member happened to mention that it was linked to pedophilia ,
No idea of the truth of the matter , only that I no longer use a default purple theme .
Purple and pink!!! LOL
Speaking of TAZ on vB though - there was the lovely orange theme.
I think TAZ's current light theme is really great. But at the same time - If the orange theme were re-introduced - I'd likely use it.
It was quite nice and another of my favorite colors!!!
