First of all, the color table is not changed behind the application's back.
A patch to InitColorTable would simply change what the default 320 mode color
table is. Detecting the active status of the window manager would make it
even more transparent since we only care about fixing things when there will
be a desktop picture drawn.

I and the person who started this thread would consider it a FIX because IMHO
the 320 and 640 mode palettes should have been consistent to begin with. The
deskpicture method you graciously supplied to us last year (which subsequently
appeared in toolbox ref 3) does not account for the fact that the two standard
color tables are inconsistent -- my current picture is colored properly for 640
mode but looks like a photographic negative when I run a 320 mode application.

Since the default color tables are fixed in stone, there are two ways to get
reasonable looking pictures in both graphics modes:

	patch out InitColorTable when the Window Manger is active
	remap the deskpicture image whenever the QD master SCB changes modes

Since most 320 mode applications install custom color tables anyway, I don't
see the InitColorTable method as a real problem. I see my deskpicture in
screwball colors a lot more often than I see application colors that depend
on the standard 320 mode color table.
