I am having trouble with the surface color and specifically of capped surfaces. To start, surfaces of individual chains are given a single color, despite individual domains having been assigned a variety of colors. I can change the colors of the surface for individual domains subsequently, so that is not so bad. However, the color of the capped surface remains the initial color adopted when the surface was created. When I change colors of the individual chains, or domains, the surface color changes, but not the color of the capped/clipped surface. If I change the color of the entire model, then the surface cap changes. But it does not respond to subsequent changes of individual chains and domains. Hiding/showing the surface does not solve the problem (though I have a dim memory of this working in the past - maybe that was the old chimera). I am only using near/far clipping planes - not front/back. ChimeraX 1.10.1 on Ubuntu and 1.8 on Windows behave the same. Thanks in advance for any insight, David
