adjusting colors in Centipede monitor

I recapped the WG 19K4903 in my Centipede, and somehow managed to screw
up all the colors. I'd prefer to avoid the full White Balance procedure
in the manual, because it involves jumpers and an oscilloscope and
fiddling with the Screen and Black Level controls and stuff. That's a
little out of my league. I just want to tweak the pots on the yoke
board to get decent colors.

I assume the easiest way to do this is with a white test screen. The
Centipede self-test mode lets you cycle through 16 background colors,
but the manual doesn't say what they are! I can't tell if one of those
colors is supposed to be white. Does anyone have a list of the
Centipede self-test background color sequence?

The pots on the yoke board are Red and Green Drive and Red/Green/Blue
Cutoff. What's the difference between "Drive" and "Cutoff"? Can I just
put some of those at max values and tweak the remainder, or must they
all be adjusted through some iterative procedure? I know enough about
the color spectrum to figure out what primary I need more or less of,
but I don't know enough about how monitors work to figure out why you
need five pots for it....

Thanks for your help!
