[Chimera-users] Changing default element colors

Hi Thomas,
It is easy to do so with a series of colordef commands, where the name  
of the color being defined is an element symbol. For example:

colordef C green
colordef Zn hot pink

If you have a very recent daily build, you can also specify colors  
with R,G,B components or as a Tk color code:

List of color names:

Subsequent coloring by element will use those colors.  The definitions  
are saved in session files, but if you want them to apply in all later  
uses of Chimera (not necessarily starting from a saved session), make  
a Chimera command file, simply a text file including all those  
commands.  Then, in the preferences (Favorites... Preferences, Command  
Line category, only shown when you are showing the Command Line),  
specify the command file as a "file to read at startup", which  
actually means as soon as the Command Line is shown.  To make the  
Command Line always shown when you start Chimera, change to the Tools  
category of preferences and check the "Auto Start" column for the  
Command Line tool.

I hope this helps,
