[css-color-5] Nested relative colors #7963
Description
3. Relative Color Syntax does not define whether nested relative colors are allowed, eg. hsl(from rgb(from var(--brand-yellow) calc(r - 100) g b) h calc(s - 10%) l), and I do not see any example of this in the spec.
Is it fine to assume that this is allowed and that you will later define a maximum of 32 level of nestings, like for math functions?
#3462 addressed maximum parentheses (function and simple block) nestings but only resolved on defining a minimum for calculations.
