Comment (Including rationale for any proposed change):
Web safe colors, web friendly colours

The access Working group GOC has recently made a requirement for web friendly colours.

They believe that some versions of magnifiers (older) only handle web safe or web friendly colours and then they dither non friendly colours. They believe that the dithering process will affect contrast. For instance, a light background that is not safe might get dithered darker, and a dark foreground might be dithered lighter. And the combination could cause lower overall contrast in older user agents. 



Proposed Change:
Discuss why or why not web safe/friendly is an issue.



Add something like:



Note: some older user agents are limited to web friendly, web safe colours. If older user agents in your baseline, use web friendly/safe colours.
