[chimerax-users] color zone colors by atom type

[Tom Goddard]

Hi Vincent,

 ChimeraX chooses the initial coloring and styles (atoms or ribbon)  to show when an atomic structure is just opened based on the size of the structure (number of atoms and chains).  This is called "smart initial display"

	https://www.cgl.ucsf.edu/chimerax/docs/user/autostyle.html

You can give each chain a single color with command

	color bychain

You might want to use ambient lighting so your maps look more 3 dimensional in images using command "light soft" or the soft lighting toolbar icon.

	Tom
