Actually, that was on purpose. That way, neither themes nor CSS will lead to the colour accidentally being overridden. I was aiming for a representation that would be completely and entirely unmistakable under any circumstances.

    this is not true. this example style should disprove your case:

    /* color links */ a, a font { color: #457; background: #eee; text-decoration: none; } a:hover { color: #eee; background: #457; } /* override <font>...</font> tags */ font, b, strong { color: #457; background: transparent; }
    there are multiple ways to override the font tags in your example. my browser does not display your text in red, as you specified, as all font tags are overridden by a user-supplied style.

    ... you'll have to aim a little higher ;-)

      Then how about <font color="#ff0000" style="color: red"> ? But I can't demonstrate that since last I checked, style attributes got stripped from user text.

        And my client-supplied CSS trumps everything you do on the web site. I wouldn't have every known you'd intended that to be differently colored until it came up. In general this is the "don't communicate solely through color" dictum.
