Looks like they're using the common [CPK method of colouring](https://en.wikipedia.org/wiki/CPK_coloring), it's not unique for J(S)Mol.

Sulfur atoms are shown in yellow.

The molecular viewer that you use is JSMol (JMol ported to the web).

Atoms are colored by element: grey C, blue N, red O and yellow S.  
If you wonder how other atoms would be colored, see JMol's [Default element colors, by periodic table](http://jmol.sourceforge.net/jscolors/).
