@svgeesus—regarding the various ambiguities in translating between CCT and RGB, etc., perhaps I should clarify that what I am suggesting here is a means to match white balance to two possible reference points: 1. Operating system white balance, e.g. iOS [Night Shift](https://support.apple.com/en-us/HT207570) and [True Tone](https://support.apple.com/en-us/HT202613); and 2. Luminaire white balance, e.g. [Hue](https://www.philips-hue.com/). Both of these encapsulate a number of assumptions, and I'm not really in a position to defend any of them so much as to suggest accommodating them, warts and all. Some example references for the above might include: 1. [Redshift](https://github.com/jonls/redshift), an open-source utility similar in function to the closed-source F.lux, which discusses its assumptions in the document [README-colorramp](https://github.com/jonls/redshift/blob/070bf1d3de78c208cbb8a393b08396bbd867e903/README-colorramp). 2. The [Matter](https://csa-iot.org/all-solutions/matter/) specification, which represents a kind of consensus for "smart home" devices, including color-programmable luminaires. According to [the Matter 1.0 Application Cluster Specification (page 111)](https://csa-iot.org/wp-content/uploads/2022/11/22-27350-001_Matter-1.0-Application-Cluster-Specification.pdf#ColorControlCluster) it uses [the CIE 1931 color space](https://en.wikipedia.org/wiki/CIE_1931_color_space). (I don't know how CSS approaches display color spaces more generally, though.) Again, what I am suggesting here is allowing web developers to employ similar assumptions to those used by existing implementations, though the assumptions should of course be explicitly enumerated. -- GitHub Notification of comment by elsiehupp Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/6582#issuecomment-1406883942 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
