Great app Does what it says on the tin! How about a "null black" for AMOLED and OLED displays?
Simple yet great. I've been looking for a simple colour wallpaper app on my Xperia. So far this is the best, no ads, just enjoy the colour. It does not limit to few colours but basically any colour as long as you've got the colour code. Using it with a colour palette.
