There are lots of very precise color standards. Though I've heard a comment
that some areas of these standards tend to lag behind technological 
developments. People who design car paints, for instance, keep coming up
with new things to do about the appearance of surfaces (iridescence,
pearlescence, etc.) that send the measurement people back to the drawing
board to find ways to describe and characterize them.

In the previous post, I mentioned a need to document the historical basis for
a recommended preference. Wasn't there a list of 3D movies posted on P3D
a few months ago? Did the anaglyph listings specify which orientation was
used for each?
