Re: [csswg-drafts] [css-color-4][css-color-adjust-1] Shielding system colors to avoid fingerprinting (#5710)

> One way to mitigate this would be to define that the system colors always return a fixed set of values via CSSOM APIs, and that forcing colors does not affect getComptuedStyle(). That way the real used color is not Web-exposed. Do we want to do that?

We'd need to use these fixed values in canvas, too, at least.

What's the current compat status of the system colors? Would it be safe to use a fixed set of colors unconditionally, or perhaps dependent only on dark mode / high contrast mode, which can be detected with the MQs? (I seem to remember that at one point the system colors were deprecated, and then they were undeprecated.)
