	Right, I absolutely agree.  The problem is what gray80 means.

	``gray80'' means 80% gray.  This is a fairly internationally
standardized color.  It does not mean "#cccccc".  You should be able to
go into a photography store (probably anywhere in the world) and ask
them for a set of grey cards, and they'll give you a set a cards with
greys between black and white at 5 or 10 percent intervals.  Your
monitor is only showing ``gray80'' if you hold up the appropriate card
next to it and it's the same color.

	In the color world companies like Pantone will charge you big
bucks for equipment to calibrate your monitors to their color sets,
which are defined for phototypesetters, etc.  This is why you use names,
you know that ``maroon'' will be the same color on your screen, on your
local prepress printers, and in the magazine ad when it hits the
streets.
