[Chimera-users] extracting chaing colors from session file?

At first I was going to suggest “mcopy” but from your description, it sounds like you have each chain as a separate model. “mcopy” is only for copying settings within one model to other models.
You can get the current atom-color RGB definitions or hex codes by Ctrl-click to select an atom (or ribbon segment to select the whole residue, if all of its atoms are the same color), showing the Selection Inspector, Inspect: atom, and then clicking the square color well to get the Color Editor. Then in the Color Editor you can see the hex code starting with # in the “Color name” field.
The square in the Model Panel shows the model-level color. Chimera has a coloring hierarchy, where if the atoms are individually assigned colors (such as with your color command), in the 3D display those colors mask the model-level color, which may be different. You can use the modelcolor command, for example “modelcolor #6168c8fb41bc #0.17” or click the color square in the Model Panel to make the Color Editor dialog appear, and then enter the hex code in the “Color name” field of the Color Editor:
There is only one model-level color per model, as the name suggests, even though the atoms and per-residue ribbon segments might be all different colors.

Is there a way to extract the colors into a text file so that I can write a command file with the same color designations?
