I put a basic Granger Chart in the files section for fun and
experimentation. A word of caution though. Do not expect all colors
to be printed correctly. Since it has been mathematicaly produced it
contains color combinations which no printer or monitor can reproduce.
This makes it an extremely useful tool for detecting the limitations
of these devices.
Personally I wish Ed had never invented these &$%&$% charts, as they cause more confusion than illumination among users. I think the warning above may actually be understated, so I'll append my own: If you are printing photographs, use photographic test colors and images. Vector colors, especially highly saturated ones like Granger Rainbows, are not of this world, and have little to do with photographic color.
