Coloring atoms in DS Visualizer from protocol

Is there an atom property I can change to modify the color of an atom before it is displayed in DS Visualizer? My protocol tags certain atoms with a specific property, then I would like those atoms to have a unique color in DS Visualizer. The "Highlight Atoms" or "Highlight Bonds" only works in the HTML Molecular Table Viewer -- it does not highlight atoms or bonds in DS Visualizer.

Thanks!
