Take into account display color temperature

[MikhailRyazanov]

Making accessibility judgements based on the sRGB model is a reasonable first-order approximation, but in practice, this is not always what people actually see on their displays. In particular, the “night light”/“night shift”/whatever mode that reduces the display color temperature, becomes more and more popular (and in general, using the 6500 K white point for indoor environments with at most 4000–5000 K lighting is not the best idea, so many people already have their monitors adjusted accordingly). Most prominently, this results in reducing the blue–black and red–white contrast. Thus I would suggest adding the display color temperature as a parameter in the contrast model (perhaps just by reducing the RGB components accordingly) or at least mention explicitly that (and how) it must be taken into account when choosing color combinations.
