Brian,
I agree with Axel's suggestion as the thing you should try first.
If that doesn't work well for you (e.g. if the time-varying selection
slows display down too much), then the next option would be to use a script
to rewrite the color scale with your own color scheme to get what you want.
Cheers,
John Stone
