[Chromatic adaptation](https://en.wikipedia.org/wiki/Chromatic_adaptation) relates to the state of someone's eye, in other words what color they currently consider to be a neutral white. This is not something a web designer can control. > The main reason I suggest the <kelvin()> color-function itself as a convenience is that Kelvin color values are increasingly used in marketing materials (for LED luminaires), A range of different colors (varying along the green-to-magenta tint axis) will have the same CCT. > the math for translating a Kelvin blackbody locus to the color on a computer display is well enough established that it should be relatively trivial for browser vendors to implement. For a color exactly on the black body locus, yes. That won't necessarily get you the same color as that produced by a random lightbulb that is labelled with the same CCT. As an example, D65 white is not the same color as a blackbody 6504 Kelvin. And display of those colors assumes adaptation to D65, not the white produced by that bulb. -- GitHub Notification of comment by svgeesus Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/6582#issuecomment-1022409417 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
