Don't know anything about it, but Dolan-Jenner makes a device that measures
the color...don't know if it's the hue, or a combination of hue/saturation/
intensity.  It was designed for fruit inspection, e.g. spin the orange and
if the average color seen is too brown or too green, throw it out.  Or if
it wasn't designed directly for that, the vendor said it was commonly used
for that.  Sounded pretty interesting...like so many other things I haven't
had time to take a look at!
