Thanks, interesting. 

This might be difficult for photoshop designers to convert their colors to since it's not in the app natively, might be worth getting to Adobe (or adding css support for HSB wouldn't hurt). 

Know any good HSL color picker tools? 

Dave

More than semantics, although the terms are often confused. Here is a page that explains the difference:

	It's HSB (brightness?) in Photoshop, so a semantics thing.

	I think you mean HSL, not HSB. But anyway, it doesn't matter. However the color was specified, the UA would convert it to HSL internally, regardless of whether it could parse HSL in the CSS.

		That would work, didn't think CSS could do  HSB?

		If you convert colors into Hue-Saturation-Lightness space, then
		lighter/darker would seem to be changes on the third axis, wouldn't
