How do I change bond colors to something besides a different hue in Coot? I can modify the colors of carbons in Coot under **Edit** , **Bond Colours...** , but that only gives me different hues. Is there a way to change the color to something less-saturated (or perhaps slightly transparent) so I can identify the "active" molecule I'm working on versus a template? The menus seem no help, I'm wondering if there's some scripting magic that can do this.

You could try other visual differences, like make what you're interested in ball-and-stick, and everything else wireframe, like in this example:

!like on this example.

.... Because, from: <

> procedure: hilight_binding_site (imol, centre_residue_spec, hilight_colour, radius): hilight-colour is specified in degrees (round the colour wheel - starting at yellow (e.g. 230 is purple))

It looks from this like you only get to choose Hue (color_map_rotation) and not Saturation or Lightness, even with the script interface.

However, text can be full RGB
