#63: Master Color Values
Revised by: Dave Lyons May 1991
Written by: Jim Luther July 1989
This Technical Note documents master color values used for the Apple IIgs
text, text background, and border colors.
Changes since July 1989: Added information on the standard QuickDraw II
640-mode color table and provided a 320-mode color table that produces
similar colors.

Border Color Values
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.

Table 1-Master Color Values
The Apple IIgs Hardware Reference documents the color registers at $C022 and
$C034, and the Apple IIgs Toolbox Reference, Volume 2 documents the master
color values.
Standard 640-mode Color Table
The description of dithering on pages 16-35 and 16-36 of Apple IIgs Toolbox
Reference, Volume 2 is correct, but some of the color values in Table 16-5
are incorrect. Table 2 lists the standard QuickDraw II 640-mode color table:

640-mode colors.
