About The Red and The Black:
I vaguely recall a red and black motif about african gods. Something about a black god being the good god, and the red god being the bad.
This could connect with the artwork nicely. Anyone knows something about african gods?
EDIT:
After a bit of research, my theory may relate to the Masai religion:
"ENKAI IS COLORED
He is called Parmuain, “many colored” or Enkai narok, “God is black”; Enkai Naibor, “God is white”; Enkai Nanyokie, “God is red”. The colors used to call Enkai are in reference with the colors of the sky. Enkai is black when the sky is black with thunderheads, which will bring rain. Enkai is white when the sky is white filled with clouds announcing the arrival of rain. Enkai is red during the dry season like the sky at that moment. The Maasai believe that when Enkai is red, it means that he is angry that is why he withholds the rain. He is no longer near. He is far away."
Black and red are present, but also white. I think I may be off with this one.
