Re: [csswg-drafts] [css-color-4][mediaqueries-5] add <kelvin()> color-function and a means for exempting from global color filters (#6582)

`kelvin()` can only produce colors on the Planckian (black-body) locus. Note that neither D50 nor D65 are on this locus (nor is the whitepoint used by DCI-P3 or by ACEScc, for example). This is why the term _correlated color temperature_ exists, to relate a given white color to the closest Planckian locus point.

Although perhaps, you want to [re-grade an entire image to a new white point?](https://tannerhelland.com/2012/09/18/convert-temperature-rgb-algorithm-code.html) It wasn't clear exactly what you were proposing.
