== css-color-adjust-1 "forced colours mode" re-introduces a privacy concern ==
I reviewed [css-color-4] and found that the deprecated systemcolors are necessarily back because of the use of forced colors mode. Even as per the current privacy and security considerations section of [css-color-adjust-1]:

Applying user color preferences via color schemes or forced colors mode expose the user’s color preferences to the page, which can increase fingerprinting surface.

It would be better if these were only available to the user-agent in order to do the color mapping.
