Hi, after updating my Xperia ray to android 4.0 the colour of the themes when set is kind of bland, not bright, it looks awful on such a phone. the Blue theme vanished at all, is there a possibility to get it back somehow? I tried to play with the contrasts on the phone, but still no such effect as it was before updating, no brightness or sharpness 
As much as I could find info on the internet, there is no possibility to install any new themes, right? Just to use those five already installed in my xperia?
Go Launcher didn't appeal to me and anyway it allows to change wallpapers only, not themes...
