Purple color of button and theme were better for this forum than this blue color, I would suggest to restore it to it’s old colour, which was having better look then current one.
Which theme are you using? There are a couple of them right now. I recently added some new ones that match the current styling of the members area better.
I’d still like your feedback so I can consider it.
But know that all the old themes are still available too, and you can switch to them from your user preferences in the forum.
Currently, Default theme button and labels are of blue color, i have changed to that purple, purple was more good looking and professional, blue button and label degrade quality of the forum.
Personally I’m really fond of the blue. Lol
