RE: Issue related to WCAG checkpoint 6.1

I don't think that the scenario you described was the primary concern of
checkpoint 6.1, but it may have been one of their concerns. It certainly is
a circumstance in which the content becomes difficult to read.

Internet Explorer 6 turns off both html and css backgound colors when you
set it to ignore background colors. It doesn't give you a choice to turn off
just one or the other. Netscape 4.8 and 7.1 appear to work the same way.
It's a little bit unusual to turn of just the css colors without also
turning off html colors, but this might occur on a page in an older browser
that supports html colors but not css colors. In this case it would be of
primary concern for users of that browser.

If only css is used, or only html colors, this conflict does not come up.
The conflict also would not come up if the html colors and css colors were
performing the same function and mimicked each other. It would come up,
though, where css and html are combined and both are required for the
document to be legible.
