There's some sort of mathematical transform to go from HSL to RGB. I really don't see why we shouldn't support a number of reasonable color spaces, HSL, RGB, and CIE are all reasonable from my point of view. It isn't alot of code. > All standard color packages easily output RGB - even XV on UNIX will tell > you the values. Let alone all of the paint and draw packages for the > various platforms. Umm, I guarantee that people will need to edit it as well, and HSL has advantages (according to the commentors) at that level. > And the browsers already understand RGB at a basic level. And it would be fairly simple to make them understand HSL. I'm guessing a few hours of work is the most that's involved. It's an input format, you can still use RGB internally. > I disagree.

The point is to make it easy for somebody to create a styled web page with either WYSIWYG tools (where the color model doesn't matter since the tool can deal with human factors) or a text editor (where it does). > Just looking at a color how would I determine the 'HSL' code/value/whatever > without a tool? OK, just looking at a color, how would I determine the 'RGB' value? Remember that I'm not a color spectrometer. You'd make an estimate at the hue, the saturation and the brightness, just as for RGB you'd guess at the red, green and blue contribution. > I'd rather not add yet another variable to the color mix. I don't see why not. Is the objection to complexity, effort of documentation, standardization issues, or compatibility? I see alot of objections to something which really looks kind of trivial, and none on things which look substantive.
