[Chimera-users] [EXTERNAL] Re: Query colors?

[Esser, Lothar (NIH/NCI) [E]]

Hi, Elaine, 

 Thanks. Yes I knew I can interactively look up colors but I need to get access to the colors in a simple .cmd script so that the 2d labels get the same font color as the corresponding model. Maybe this is not possible. What algorithm (mentioned in the doc that it exists) do you use to generate new model colors ?

Thanks, 
Lothar

Hi Lothar,
Interactively, you can look in the Model Panel and click the color square for that model, which will bring up the Color Editor containing the color.   Or, if you select part of a model and look in the Selection Inspector molecule attributes, it will also show that color well.

Programmatically (if you need code somebody else would need to address that), it is the model attribute named "color"... but you can list them as R,G,B  in the Reply Log with command:

list models attribute color

Also, the first 9 colors are listed in the description of the New Molecules preference "use new color for each model":
