Hi Elaine, OK thanks! It is pretty specific but I saw a figure apparently from PyMol like this and rather liked it. Just to clarify, what I was trying to describe is as in the attached. Just hacked in photoshop on a couple of the central strands to illustrate. Not essential, but maybe chimeraX will be able to do this :) Thanks, Kyle

Hi Kyle, Sorry, there isn’t any option to color the edges of strand ribbons differently. A secondary issue is that if you are thinking of the broader sides of the strand representation, inside vs. outside is not clearly defined. Even if it were, however, there isn’t an option to color any sides of strand or coil ribbons differently from others… there is only the inside color for helices.

Now, you might be able to do something very fudgy by opening the structure twice and changing the strand ribbon scaling (in Ribbon Style Editor, in Tools under Depiction) of one copy to have slightly broader but thinner strands, and in a different color than the first copy. However, I haven’t tried it myself and it might look very bad. This also would not get at coloring the broad sides differently, only the edges of ribbons with a rectangular cross-section.

Ribbon Style Editor, see “scalings” <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/ribbonstyle/ribbonstyle.html>

Dear Chimera dev, Sorry if I missed this in the documentation and online…

Is it possible to make the inside and side edges of strands a color independent of the models coloring? Akin to using ribinsidecolor white to color the inside of helices white, I would like to color the inside and side edges of strands white.

Thanks for your help as always! Best wishes, Kyle
