I have about 10 colours from the system palette on my desktop including
coloured windows and menubar; I have a picture that uses a special palette
of 240 colours; and my monitor can display 256 colours.

So there are enough colours to display the desktop and picture under
MultiFinder with exact colour matches. How do I do it?

I tried creating a palette with 240 tolerant colours. When the tolerance
is $0000 the picture displays perfectly but the desktop colours are wrong
and the disk icons down the right side disappear. Why? 256 colours is
enough for everyone. When I make the tolerance $1500 the desktop colours
are right but the picture has some colours wrong and the desktop icons are
missing. When I make the tolerance $4000 the desktop colours are perfect,
the disk icons are present, but my picture is very distorted.

Am I expecting too much from the Palette manager? Do I have to manually
copy those 10 colours into my palette? I don't even know what colour they
are or how to find them. I thought the palette manager handled that sort
of thing. Am I spelling the word "colour" wrongly?

Thanks for your help
