Hello,

I imported an x,y,z model of water molecules into Chimera.

I want to create an image of my water structure so I am setting the background to grey.  That works.

But I would prefer to set the hydrogen atom colour to light grey.   I can’t work out how to do that.  I can select each individual atom, and then colour edit it but that will take ages. 

Is there a simple command line solution?

Thanks
