When I set the screen display temperature lower, say 3000 K, the white goes yellow as expected. However, blue colours, or maybe any color other than around white, are not affected by the filter, making the overall screen appear blue-yellow. This becomes disturbing, distracting, and unrealistic whenever there is a blue item on the screen. I guess this is done on purpose because decreasing the blue output of the screen, no matter what colour is displayed, would be more easily achieved, I suppose. So, is there a way to make blue colour not appear crudely when using lower screen colour tempretures? I might be able to follow some well explained command instructions, though I am a novice user only. Thanks.
