==========================

exactly.

of course no single thing can solve all problems, but this seems like a 
great solution to a particular problem. the fact that it might *only* help 
95% of the people who want to make use of it doesn't make it a bad idea... 
as long as it's meant to compliment the current system, not supersede it 
(and i don't hear any calls for throwing away the current system).

the issues become standardizing colors and sizes... it would be great to 
hold two pieces of paper next to each other and (if the squares are the 
same size) identify almost immediately if it's a match or not.

with only 16 colors, it allows for error in color accuracy of displays, 
printers, etc.

an observation... here in the states a standard business card is 2 x 3.5 
inches (are they 50 x 90 mm in the civilized world?)... an SHA-1 hash 
produces 40 characters (16^40)... if the whole width of the bottom (or 
top) of a business card displayed this "rainbow code" then each character 
could be represented by a 2.25 mm square (or a bar that's 2.25 mm wide).

if used in a front-end, it would be great to have an option to resize that 
part of the display so a card can be held to the monitor and the sizes 
match.
