I so seldom use a color display on this monitor that the brightness
was set pretty low.  Now it looks somewhat better.

The dark colors are so dark, though, that any mix with a brighter
color has about the same effect regardless of the dark "color".

I would judge the *useful* pallette to be much less than 131 colors.
