Hi all,

It would be great if somebody could clarify the following:

Section 9.1 of WCAG10-CSS-TECHS 
says to use numbers, not names, for colors.

Section 4.3.6 Colors of CSS2.1 Specs 
says that there are 17 colors keywords (color names. right?)

So, why avoid colors names if they are legal according CSS21 specs?
How does colors names CSS value can have an effect upon the contrast?
