[Chimera-users] How to change colour of H-bond between atoms

Dear Chimera Users, There is a hydrogen bond between, say, H20 of a ligand (LIG,res no: 240; this H-atom is attached with N atom of LIG) and O atom of GLU 120 residue. There are other hydrogen bonds too, but I am interested to change the color of that H-bond only to, say, red. I tried some like bondcolor red :240@H20 But, it is not working. Any suggestion might help me. Also, is there any way to change width of the H-bond? Thank you, Mahendra Thapa University of Cincinnati,OH
