Here is another tip for you Angus and all ATI users (available for Nvidia too but not sure how to do it).
Go into Cat Control Centre, Open Digital Panel, Open Avivo Colour and move the slider on Saturation from 100 up. The slider goes up to 200 and you should select a setting where you feel comfortable. I have mine all the way up to 200 but Pooka felt the colours were too vibrant for him at the full 200 setting and has it lower. In any event, by increasing it above 100 you will notice a big difference in brightness and colour vibrancy.
