we do have a private implementation of a HSL to RGB converter in 

As far as khtml stands, having HSL in kdelibs would simplify this code.

Also, I think that calling 500 lines of mathematical code bringing nice 
features a 'bloat' is not just preposterous. It's grotesque.

Your argument about the strengh of HSL with regard to lighten() and darken() 
is especially compelling, and is what convinced W3C too:

  "Advantages of HSL are that it is symmetrical to lightness and darkness
   (which is not the case with HSV for example),"

In light of this, I fully support this addition.

(as for my clame to expertise, it is restricted to coming up with 
khtml::hasSufficientContrast's algorithm using hsv, which was a pain and 
would very likely work better in HSL)
