RE: [PyMOL] CMYK colors

[DeLano, W. <wa...@su...>]

Thanks for the suggestion?

For now, why not just redefine the existing colors?=20

No need for a leading underscore...

set_color green=3D [0.00 , 0.53 , 0.22]

etc.

Note that there are default atom colors such as "carbon", "nitrogen", =
"oxygen", "hydrogen", "sulfur", etc. which should also be redefined.

set_color carbon=3D [0.00 , 0.53 , 0.22]

etc,=20
