Hi Vincent,

  Check that your map is model #2 and your atomic structure is model #1 by looking at the id numbers in the Models panel.  Also if you hover the mouse over an atom you can check that your atomic structure as chain A.

  I see that If you get the model numbers wrong the command does not warn you that nothing was colored.  I will fix that so it gives a warning.

Dear ChimeraX users, 

I just subscribed so apologies if this has been asked before. 

When is type the command: color zone #2 near #1/A distance 5 sharpEdges false farColor blue

I have the volume #2 in blue with chain A colored by atom type: i.e. with carbons in sand, oxygens in red, nitrogens in blue. 

I tried to follow the tutorial on youtube, downloading the model and emdb like in the tutorial, and it does work like the tutorial, meaning colored by chain. 

I am wodering what is going on and how to fix it? I've seen this behavior for my protein, on a PDB refined from Phenix, or from a download from the rcsb. 
I don't see anything special on the PDB, all the atoms are listed normally. 


Is it possible to assign a specific color per chain using this command? 


Thank you for your help. 
best
Vincent
