Very nice.  These look better than what I was fooling with a while back.
I'll try to envision the function and the "color space" that you're graphing
this in - but it's too early and I've not had enough coffee yet.   ;)

Hmmm.  I don't know much about this.  I've only seen some discussion of "color
matching" of film frames in the LOTR extended extras.   Is that the kind of
thing you're talking about?
"The usual"?  For what?  Most movies, or that series?

"A POV implementation...."   I'm not sure what you mean by that.
A way to force the color map to be limited to that range of colors?


Something interesting that I noticed with these two is that the top graph has a
ring of missing black, and the bottom one has the black present, and all the way
around.

There was also another thread around that time where someone was processing
video and doing an animation of the color palette - can't find it at the moment.
