GRAPH screen

The default palette of ICE (and the C libraries as well) is the xLIBC palette, which looks like this:

However, it's quite hard to remember all those color values. That's why ICE installs a second useful feature into the program editor. If you hit [GRAPH] while inside a calculator's program editor, you get a screen with all the colors, as well as the formula to calculate the color value. This is to very easily pick colors without printing the color chart or remembering the most important colors. Note that you can't select a color, only see them with the corresponding values.
