the screen, does have a filter, if u look at 1 when its off it has a orange tinge to it, u could take the dash off and take the screen out, then change the filter to a clear one and it has a back light, so u could take the screen apart and change the backlight, will be alot of hassle, easiest thing to do would be find 1 of the many mobile phone sites that change the colour of the backlights and leds etc, send it to them to get it changed wont be cheap though should think about 30- 60 quid
