The EDGE may be able to be configured to use a lot of colors, but I guarantee you that
1) the device LEDs won't be able to display them,
2) you won't be able to tell the difference between all of the ones the device may be able to display, and
3) the printer you use to print the cheat sheet won't match the color spectrum of the LEDs that the EDGE is using to display the configs.
Lastly, I'm being silly here, but there is a mild point to this.. but where is OBsIV's sense of responsibility to the environment? Shouldn't he be shying away from supporting the killing of trees to support his product? <grin>
