> CCT is an absolute colour description. Almost. The series of CIE Daylight standards are absolute color descriptions, yes. The daylight standards are not actually on the black body locus, but somewhat close to it. A whole set of colors can be on the line between 6504 on the black-body locus and D65 and these will all have a CCT of 6504 but they will be different colors (varying in a magenta to green direction). But anyway, D65 is a absolute color description whose chromaticity coordinates are fixed. > In sRGB, 6500 kelvin is essentially [1,1,1], but in another colour space (one with a white-point of D50, for example), the same 6500 kelvin has now changed 'colour', No, the color hasn't changed. As you said, or were I think trying to say, D65 is an absolute color. > it would now be represented as something more blue than [1,1,1]. It has changed representation, because it is now in a different colorspace. But it is the same color. -- GitHub Notification of comment by svgeesus Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/6582#issuecomment-996062300 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
