Hi Atsutoshi, If you want the "element" coloring (oxygen red, nitrogen blue, ... ) one way is to use the menu item: Actions... Color... by element Actually there are many different ways to color atoms, ribbons, surfaces, and other things. The many ways are listed in this manual page: http://www.cgl.ucsf.edu/chimera/1.2304/docs/UsersGuide/coloring.html In Chimera, you can search for help using the menu item: Help... Search Documentation for example, if you search by "coloring" the page I mentioned above is hit #2. There are also tutorials for new users of Chimera (Help... Tutorials). I hope this helps, Elaine On Oct 23, 2006, at 10:28 PM, Atsutoshi Okabe wrote:

Hi,

I visualized one ligand molecule (a kind of sugar) written by PDB format within chimera.

But all atoms have non color(attached file ) I want to color these atoms (i.e. the oxygen has red …)

Could you please teach me how to color atoms?
