Thanks very much, guys. What Bob mentioned (color range all) solved my
problems. The thing is a unified color span is hard to define. If the range
is to large, the coloring would be hard to discriminate the compound with
slight partial charge differences. Range all is exactly what I want, which
magnify the differences.

Cheers,
