I love the keyboard on my WSL XVision (in Europe aka Advent Vega). But the colors are awfull. Grey on white, that is not very practical. So I made a small graphic mod to the keyboard. I tested it only on my WSL XVision, no guaranty if it breaks your device or destroy your SD card data. For me it works fine.
I attached some screen shots.
