This Technical Note documents master color values used for the Apple IIGS 
text, text background, and border colors.

There are times when you may want to make parts of the IIGS Super Hi-Res 
screen the same color as the text, text background, and border colors.  This 
is particularly useful when using the Apple II Video Overlay Card.  Table 1 
lists each color using the names from the Control Panel CDA, the color 
register values used for that color by the color registers, and the master 
color value used for that color by the Super Hi-Res screen.
