Hi Mark,

  The color zone command can be used multiple times where it keeps the previous colors that are beyond the distance range specified with the most recent command.  You use the color zone option "farColor keep" to do this.

open 8of8
open 16850 from emdb
color zone #2 near /A-F distance 10
color zone #2 near /K distance 10 far keep

This is described in the color zone documentation

https://www.cgl.ucsf.edu/chimerax/docs/user/commands/color.html#zone

If you change the map contour level after coloring, only the coloring done by the most recent color zone command will be applied to the new surface.

Hi Elaine

Yes, that worked. I colored each set separately and then applied to the surface as you kindly suggested.

Thank you.

Hi Mark,
This is intentional in that it will always recolor the whole surface according to the current settings.  If you wanted multiple different colors at the same time you would color all the atoms accordingly, different sets in different colors, and then "color zone" the surface in one step to make the surface match.  Especially if one adjusts the zone distance, you would want the regions that no longer meet the criteria to no longer be colored, so the whole surface needs to be re-evaluated... at least, that is how I understand it.
I hope this makes sense,
Elaine
