CartoonStyleSpec

A visualization of protein or nucleic acid secondary structure. Applying this to other molecules will not show anything.
In nucleic acids, the base cylinders obtain their color from the atom to which the cylinder is drawn, which is 'N1' for purines (resn: 'A', 'G', 'DA', 'DG') and
'N3' for pyrimidines (resn: 'C', 'U', 'DC', 'DT').
The different nucleobases can therefore be distinguished as by setting the colors
of each of these atoms. The backbone color is set from the 'P' atoms ('O5' for the 5' terminus).

$3Dmol.download("pdb:4ZD3",viewer,{},function(){
                  viewer.setBackgroundColor(0xffffffff);
                  viewer.setViewStyle({style:"outline"});
                  viewer.setStyle({},{cartoon:{}});
                  viewer.render();
