In response to a fair few requests by users we've recently changed our theme to a lighter design, hopefully increasing legibility and making the site a little easier on the eyes.
The original site was a much darker design, initially aimed at the gaming community more than anyone else, hence the darker background. Over the last year or so we've gradually lightened the colours used and then finally jumped in with both feet and made the whole site lighter, rather than just the background. It really helps on the 'Browse by category' page, highlighting the shades of blue used to show how 'busy' each section is.
So goodbye Retro hello Future!
