Re: [csswg-drafts] [css-color-adjust-1] Specification can define non-author color adjustment behavior more clearly (#13460)

Thanks — I agree the current text captures the baseline risk of UA exposure of user preferences via getComputedStyle().

My concern is slightly narrower: extensions, assistive technologies, or managed policies can introduce additional distinguishable rendering states beyond default UA preference exposure (e.g., non-default palettes, consistent cross-origin overrides, or systematic use of forced-color-adjust). These outcomes are observable through the same mechanisms and can add fingerprinting entropy or create ambiguity about the source of the rendering.

I’m not suggesting a major change... just that clarifying the privacy note to include “other non-author/UA-mediated overrides” would make the scope explicit and avoid the interpretation that only baseline UA preference exposure is relevant.

Although, I agree this isn't super critical, and would leave it upto the team to decide. :D
