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

+1 that this is an information disclosure risk, not just a fingerprinting risk, especially if (as the IRC log above suggests), there are known direct cases of sites using getComputedStyle to detect whether the user has an accessibility mode turned on.

I would think that for color (as opposed to other properties that affect layout), lying in getComputedStyle is an effective mitigation, as in :visited/history sniffing.

In this case it might also require limitations on new media queries.
