Thanks very much for your detailed instruction.
If I use rainbow models red,blue
then can Chimera produce a color panel to denote the colors used?

There isn't really a default just for ensembles. The default behavior
is to use a different color for each "model" (generally each structure
file makes one model). It is in the preferences, New Molecules
You can use "rainbow" for coloring different models or chains or
residues, gradually changing from one color to another. You can use
either the "rainbow" command or the "Rainbow" graphical interface.
For graphical interface, choose Tools... Depiction... Rainbow. In
your case you would want to use the "model" option. You can change
the colors by clicking the squares and using the Color Editor.
Similarly, you could just use the command "rainbow models" to use the
default coloring, but there are additional keywords to use different
For example, if you really only want red->blue and not all the rainbow
colors in between, the command would be
rainbow models red,blue
Here are the built-in color names:
