@annevk Yes, as smfr [noted on the call](https://lists.w3.org/Archives/Public/www-style/2021Jan/0014.html) implementations would have to taint the canvas, which also means fingerprinting mitigations here would be very complex to implement as well.

IIRC you _can_ choose your own colors (and for some users this may be necessary), but there are several pre-configured themes.
