oke .. now its clear.. the subpixels RGB can be turned off or on in low powermode only.. so there are only 8 colors available 000000 ff0000 00ff00 0000ff 00ffff ff00ff ffff00 ffffff the only thing i noticed is that only ffffff grants a smooth font face.. all the others look a little bit odd (maybe because the pixels that are lit are too little and to far away from each other)
