I applaud the addition of HSL processing to CSS3. Adding something like HSP would take this to its logical conclusion. HSP is Hue / Saturation / Perceived brightness, which is even more natural to work with. When working inside an HSP colorspace, more visually pleasing results are reached more intuitively. Specifying colors in raw HSL tends to be a little "lumpy" in terms of saturation and color "feel". http://alienryderflex.com/hsp.html http://alienryderflex.com/hsp.html
