I'm not sure what is meant by "RGB percentile values" - percentage values in rgb functional notation ("color: rgb( 100%, 0%, 100%)") are supported by both Internet Explorer 4.0 and Navigator 4.0. Rgb functional notation was not in IE 3.x. At any rate, my objection is that a new color specification type is a non-optional technology. Envision loading a page that sets its text color using HSL, and has the background set to "black" (the named color). It makes sense to do this - you know you want a solid, normal black background, so you use the named color 'cause it's easy, and you want to tweak the foreground color, so you use HSL. Now look at the page in a browser that may support all of CSS1, but none of CSS2. Look at it in IE4 and Navigator 4. It's black-on-black. This is much worse than not supporting the right semantics for margin values, or not supporting font variants, or even not supporting positioning - even the smallest embedding system UA could support enough CSS to understand "black", and show you black-on-black because it doesn't support HSL. HSL may be a wonderful thing - but putting it into CSS >1.0 may not be. Put it in the tools. Heck, if someone sends me a Javascript/C/C++/Java algorithm, I'll put support for it in my DHTML CSS editor for IE4.
