Thanks! So if I understand correctly, the intent of the spec is to: 1. assume CIELAB is relative to D50 (as defined by CIE, not ICC); and furthermore, 2. the method of computing sRGB ↔️ CIELAB (in particular, the choice of matrices) is non-normative. In regards to 1, this sentence: > D50 is also the whitepoint used for the profile connection space in ICC color interconversion, I think may benefit from clarifying the distinction between the ICC definition of D50 and the CIE definition of D50. In regards to 2, I'm a bit concerned that I've seen many variations on the matrices used to get sRGB ↔️ XYZ<sub>D65</sub> ↔️ XYZ<sub>D50</sub>, or direct sRGB ↔️ XYZ<sub>D50</sub> pairs, and I wonder whether some well-defined matrices in the spec won't lead to more consistent implementations? -- GitHub Notification of comment by danburzo Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/2492#issuecomment-378057775 using your GitHub account
