   Agreed.  My guess is that it's zero degrees, based on my work with
Photoshop.  However, do I know where yellow is?  How about green?  (The
answer in both cases is "no.")

   Sure, why not?  Whether these are useful to everyone in the world is
beside the point.  I can mostly think in RGB, but not everyone can.  The
more ways we have to specify colors, the better, if you ask me.  So why not
put HLS and LAB (and whatever else) in front of the Working Group and find
out what survives, and what gets postponed?
   Never mind the fact that we're pretty much stuck with the 216-color
"Web-safe" palette for the forseeable future...
