The gray Wirechan theme looked way better in the original.
Looks fine to me. Functional and understated. There's something cool about the pale candy-apple green just peeking out from under a neutral gray.
What did it look like before? Have any screenshots?
It's not the color scheme that changed; it just doesn't look as good on vichan unfortunately as unhelpful as that is. I don't have any screenshots.
