I would like to propose closing Bugzilla issues #734[1] and #739[2] 
relating to the CSS technique concerning color.  The original technique 
recommended using numeric color values rather than color names when 
specifying colors. There has been a significant amount of discussion about 
whether or not this is an accessibility issue or not do to varying support 
for color names in browsers.   I did some investigating of color name 
support in some screen readers and browsers and found that most support 
the full 140 color names specified in CSS 3[3] as well as numeric color 
values.   CSS technique 7.1[4] has been updated to state: 

Use CSS color keywords or a numerical hex value to specify colors. 

And now includes User Agent specific information about support of colors 
by JAWS and WindowEyes.   While the technique is somewhat ambiguous - you 
need to use color names or numeric values (although the technique favors 
numerical hex values over decimal rgb values)- I think it is worth keeping 
since the additional User Agent information is helpful. 

I propose adding additional, general browser information to the User Agent 
section of this technique and closing issues #734 and #739:
When using color names, use only those from the x11 color names list in 
the CSS3 Color Module spec[3]  or the basic 16 HTML 4 [5] color values. 
Using numeric color values generally provides the best support across user 

The alternate option is to close the issues AND remove the CSS technique 
since it is more informational than a specific requirement. 

Are there objections to closing the issues and keeping the technique?
