Yes agreed, although we say it's "legacy", we should have an example saying "all <color> values compute to the rgb(, , ) format".

as getPropertyValue(_color-property_) does return a string helpful it would be to state this as such. Certainly when developers attempt to compare these values.

Also hinting to this fact in a separate section would be a good thing. comparisons of color values in in JavaScript values should be discouraged as JavaScript currently has no build in color management or classes of functions.

• This is a serialization issue, which is part of API pages, and should be tracked with #32734.

For now, on the color_value/rgb page, we can add a note below the syntax section saying the values are still being serialized using old syntax and add a detailed note in https://developer.mozilla.org/en-US/docs/Web/API/Window/getComputedStyle#notes.

I'll raise bugs in browser repos to make serialization use new syntaxes.

I wish you success but I doubt it would be possible. Web compatibility is a long and winded story and there surely will be websites relying on the precise serialization format of colors.

True there are seemingly endless ways of how to specify colors. But is JavaScript I'm talking about. There seems to be only one standard way of what is output in getComputedStyle().getPropertyValue() as far as colors are involved.
