cdoublev has just created a new issue for https://github.com/w3c/csswg-drafts: == [css-color-hdr-1] Clarify parsing and serialization of `hdr-color()` == https://drafts.csswg.org/css-color-hdr-1/#hdr-color-function > The two headroom values must not be the same 1. What should happen if the two headroom values are the same? Should the function be invalid? 2. In `color-hdr(0 xyz-d65 1.2 0 0, xyz-d65 1.2 0 0)`, are they the same value? Should the default value be `0` when omitted, as is suggesting the [CSSWG discussion](https://github.com/w3c/csswg-drafts/issues/11616#issuecomment-2654776232) that led to the resolution to add `color-hdr()`? 3. I think its `<color>` components should serialize as resolved in #10328 but since the corresponding spec edits are still pending, could it be clarified in this issue? --- I suspect that `hdr-color() = color-hdr(...)` is intentional. But that seems confusing, imo.
