KHTML, the Konqueror rendering engine, has received another upgrade – and with it, more implementation of the still-officially unannounced CSS3!
According to the release notes, KHTML 3.5.5 now has support for the HSV/HSVA color values. I must confess to being a little baffled by this; the CSS3 color module names HSL/HSLA values (of which HSL is supported), but not HSV/HSVA. Perhaps someone more au fait with colours could help me out on this one.
Also now supported, apparently, is the outline-offset property – which does exactly what it says; offsets the outline around a page element.
Please bear in mind I haven’t tested these, yet.

The release notes are actually incorrect in stating that KHTML now supports HSV/HSVA. What they support are the CSS3 HSL/HSLA values, porting David Carson’s code from WebCore. It is the same code that was blogged about here (http://www.css3.info/blog/hsl-and-hsla-implemented-in-webkit-nightly/).
I do not use Konquerer but am interested in making my code as universal as possible and since I’m already adding 3-4 variants of the latest codes to cover -moz-, -webkit-, opera and IE then 1 more wont hurt!
More relevantly however I would suggest that the HSL vs HSV refer to the same thing (i.e. Hue-Saturation-Luminance / Hue-Saturation-Vibrance). I’m not a Photoshop expert or anything but I would guess that in this context ‘Luminance’ and ‘Vibrance’ are interchangeable.
Feel free to correct this if I’m wrong though.
++ Great website btw :D ++
– nb: Whoa!! Just realised how old this post is, hmm I wonder if my comments are still relevant or useful to anyone? – Oh well…
@Chris: It’s a common misconception–HSV and HSL are different models. Their values for H are similar, but the calculations for S and Value/Brightness (or L) are markedly different. Wikipedia has a fair explanation ( http://en.wikipedia.org/wiki/HSL_and_HSV ), but I don’t think the images do it justice. See, e.g, http://www.codeproject.com/KB/recipes/colorspace1… for an explanation in C# (with pictures).
