Have you never seen users say

   p { color: orange; }


The color 'orange' is supported by UAs because they support the X11
colours and 'orange' is one of those.

In practice these colours have been supported anyway, so this point is
moot unless you are aware of a fully CSS2 compliant browser (or even a
fully CSS1 compliant browser).

Since color names are *exactly equivalent* to RGB values (each name is
given an exact RGB equivalent, e.g. 'red' is the same as 'rgb(255,0,0)'),
I am not sure I understand the reasoning behind this technique.

A fair comment.

I do not disagree.

We want to support 'color:orange', though, because authors are already
using it, and UAs are already implementing it. What subset of colours
would you suggest we use instead?
