Re: [csswg-drafts] [css-color-4] Channel clipping breaks author expectations, especially when using 'perceptually uniform' spaces (#9449)

I agree, I used the picture stuff as a general example, but maybe it would help to define more precisely what use cases within CSS colors gamut mapping is meant to aid and why. Are there missing cases? If there is agreement on that, I think the rest will fall into place.

From the perspective of generating tones and providing good contrast, I think chroma reduction wins, but are there other cases that aren't being considered? I know surprising users was brought up, but I think a user can be surprised in both ways in the future, either by colorfulness or by lightness.

I tend to fall in the camp that preserving lightness solves the more important issues as far as CSS is concerned, creating tones and contrast. That is of course based on how I'd like to use it. I acknowledge that other solutions are useful in certain cases, but I haven't yet seen a clear example yet outside of you can get more vidid colors, but as you noted, you can construct vidid spot colors easily and vivid gradients as well. Maybe there are use cases I haven't thought of?
