Superpose many pdbs, use different colors, but keep heavy atoms in a different color.

Hi.

I superposed 5 pdbs mutated on positions 1, 45, 67. The idea is to superpose the backbone structures and highlight the sidechains of those 3 positions only. For this i'm using 2 representations. One where each structure has a different color and display ribbons, and other where the sidechains are highlighted. The heavy atoms should assume the color of their structure (same as the ribbon), but the heavy atoms should keep their default colors (O=red, N=blue, S=yellow, etc).

This is my line representation and selection for displaying the sidechains:
o.addRepresentation("line", {sele: "(1, 45, 67) and (not hydrogen)"})

However, when I assign each structure a color, the heavy atoms in the sidechain lose the default colors and assume the color of the structure.

I tried a ColormakerRegistry like this:

var schemeId = NGL.ColormakerRegistry.addSelectionScheme([
                ['green', "(1 or 45 or 67) and .C"], 
                ['blue', "(1 or 45 or 67) and .N"],
                ['red', "(1 or 45 or 67) and .O"]
], "Name for the structure");

but no luck.

Is there a way that I can keep the default color for heavy atoms on every structure, regardless of the color of carbons?
Thanks in advance

The element colormaker does this, if you set the colorValue to a color name like "green" (or hex code like "#0F0") then it'll color the carbons in that colour and all the other atoms their default element-based scheme.

Codepen example

You can combine element colorscheme with a selection for specific atoms

Worked like a charm. Thanks!
