Re: [csswg-drafts] [css-color-5] Clarification on how `channel keywords` with multiple specified types work (#7876)

> Why can't we have it be a number or percentage depending on which one type checks? 

CSS used to have a `<number-or-percentage>` type but it no longer exists. @tabatkins said that [it can't](https://github.com/w3c/csswg-drafts/issues/7876#issuecomment-1282797648) and could explain better than I why that had to be removed.

> For example, with `oklch` you'd have to do `calc(l + .1)` instead of `calc(l + 10)` for lch because the number range is [0, 1] instead of [0, 100]. 

For 10% lighter I would probably do `calc(l * 1.1)` in both cases.

But I do see your point, and sorry for the breaking change.
