text: user7371: What does the yellow mean in this image of a SARS (coronavirus) protease from the Virus Pathogen resource database? It's from https://www.viprbrc.org/brc/
  
  
  user266: 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.
