Color schemes can be applied to structural nodes to modify the colors of atoms and bonds. Color schemes can also be applied to Visual models, e.g. to colorize the secondary structure.

Color schemes may be used to e.g. assign a constant color to a node, colorize atoms by residue, chain, etc, or based on some node property (e.g., temperature factor, atom velocity, etc.).

When a color scheme is applied to a node, all the node’s descendants are affected.

Three types of color schemes are available:

Constant: the same color is uniformly applied
CPK: the classic Corey-Pauling-Koltun color scheme
Per attribute: the color is determined based on an atom attribute (e.g. temperature factor, residue, etc.)
