Re: [css-colors] Specify the System Colors colors

So according to the tests from Simon, all browsers support some kind of color sets that are not interoperable at all. There is just one exception with Android and iOS and we don't know if that changes with one of the next versions.

Do UAs not see any privacy concerns? If so, why does the view between the WG and the UAs differ? Are the color profiles actively used as spoofing mechanism? And what does the attacker get for relevant information from the color settings (even if they would be OS theme dependent)?

When David says Firefox can probably not follow the spec wording, then the idea of default colors (and the potential privacy threat) can not be addressed at all.

Greetings,
Dirk
