I figured out how to change the panel colors of specific alcoves, but I want to change the color of the alcoves themselves. I want to make the alcoves in the list [S[0],S[1],S[2], S[0]S[2]S[1], identity] green. Below is my code just making the panels green.
import coxeter
L = RootSystem(["A",2,1]).ambient_space() plot_background = L.plot(fundamental_chamber=True,roots=False,coroots=False,\ fundamental_weights=False,)
W = L.weyl_group() S = W.simple_reflections() identity = W.from_reduced_word([]) alcoves = [S[0],S[1],S[2], S[0]S[2]S[1], identity] color = lambda i: "green"
plot_alcoves = L.plot(fundamental_chamber=False,roots=False,coroots=False,\ fundamental_weights=False,reflection_hyperplanes=False,\ alcoves=alcoves,color=color,alcove_labels=True)
(plot_background + plot_alcoves).show(frame=False, axes=False)
