Security review requested for CSS Color 4.

Hi there,

CSS Working Group requests Security review of CSS Color 4.
https://drafts.csswg.org/css-color-4/ 
<https://drafts.csswg.org/css-color-4/>

This specification is used to describe the colors of various items on 
Web pages, such as text, borders, and so on. It builds on existing 
capabilities in CS1, CSS2, and CSS Color 3.

The responses to the Self-Review Questionnaire: Security and Privacy 
<https://www.w3.org/TR/security-privacy-questionnaire/> can be found on 
this GitHub issue:
https://github.com/w3c/csswg-drafts/issues/5499 
<https://github.com/w3c/csswg-drafts/issues/5499>

We would prefer responses and discussion to also happen on that issue.

The specification at Working Draft; it is not complete, but major 
portions are stable and are seeing active implementation. Our 
anticipated timeframe to move to Candidate Recommendation is two to 
three months, depending on how long it takes to close off remaining 
issues of course. Meanwhile we are starting wide review in hope of 
getting any major issues addressed before we publish an updated WD for a 
stable Wide Review draft.

Thanks for your consideration.
