I see.  The above code is equivalent to doing “Tools->Utilities->Color Editor”, not clicking on a model panel color well.  There is no direct hook into those color wells, so doing what you want requires some fancy footwork.  Here’s my best shot:


import chimera
from chimera.tkgui import FakeWell
class ModelWell(FakeWell):
	def showColor(self, color=None, multiple=False, notifyPanel=True, doCallback=True):
		if multiple or not doCallback:
			return
		for model in mp.selected(moleculesOnly=False, groupsOkay=True):
			if color == None:
				model.color = None
			else:
				model.color = chimera.MaterialColor(*color))
mw = ModelWell()
# The ‘mp’ variable holding the model panel instance must already exist 
# when activate called
mw.activate() # pops up the color editor
