When I worked in the Color Standard indusry in the 1980's we calibrated all 
of our monitors before shipiing a turnkey color system using a grayscale 
strip provided by Kodak. We also provided mapping of colors for printers 
using matched colors and dithers. The printer colors were dithers matched to 
the calibrated monitor. We worked with Targa Boards and Targa Board Clones 
like the EV680 form Everex and 16 bit color in the days before TrueColor 
VGA. We also calibrated VGA moniors using the same greyscale technique when 
ATI first produced the Wonder XL circa 1990-1991, and also for Evrex's first 
TrueColor VGA's.

Some of the printers we supported were high-end Kodak 5 x 5 photo printers, 
and Tektronix theraml wax printers.

The reason I am telling you all this is that in order for any color 
sonsistency on real video of any kind at all, your monitor must be 
calbrated. Yes Phosphors get old and dim, and not all monitors are created 
equal but the draned things don't calibrate themselves. But an accurately 
calibrated monitor using some kind of accurately printed standard will be 
consistent whereas fiddling with the dials at random does not work worth a 
darn.

That's my rant for today.
