Re: [csswg-drafts] [css-color-5] Findings on SCSS function usage to inform direction of Color 5 (#5782)

> I've felt that we should implement these with existing popular web color spaces today if the input colors are within those color spaces. I.e. if the input is RGB or HSL, we should still be able to make adjustments. This would make implementation in a timely manner much more likely

That means:

- throwing away perceptual uniformity. One clear drawback of HSL, and a reason people only use `lighten()` and `darken()`, is that changing the hue also changes the actual, visual, lightness. And the hues are bunched up some places and spead widely at others.
- throwing away the visual benefit of manipulation in linear-light spaces, because computations in gamma-encoded space have the well-known problems of mixtures being too dark and hue shifts occurring that should not.
