"CPK" stands for Corey-Pauling-Koltun. It commonly refers to a color scheme for the elements that originated in physical models developed by Corey, Pauling and Koltun. In this color scheme, carbon is gray or black, <font color="red">'''oxygen is red'''</font>, <font color="blue">'''nitrogen is blue'''</font>, and hydrogen is white. The command "color cpk" applies this color scheme in popular molecular visualization programs such as [[RasMol]], [[Chime]], and [[Jmol]]. The complete set of element colors used by Jmol is available at [http://jmol.sourceforge.net/jscolors/ Jmol Colors], where the colors used by RasMol are compared with those used by Jmol.
