Missing support for HSB / HSV

[ChristophLabacher]

HSB might not be supported in CSS, but it is still extremely important as Sketch and Photoshop show values in HSB, not HSL.

Interesting. Again, at this point, this is more of a renderer kind of issue (as long as we don't actively parse color values in the parser. The question is: what should we do about this. I think this needs additional discussion. @theflow @rockitbaby

@ChristophLabacher We've been talking about "really" parsing identifiable color values and being able to convert them to rgb on the fly, so I'm closing this and turning it into a Trello ticket for future reference, okay?
