Outdoor Alabama warns that smaller indigo snakes are easily taken for the common black racer. A: Red, orange or cream (some all black) in the Eastern Indigo Snake; white in the North American Racer. B: Very big and thick, glossy blue-black in the Eastern Indigo Snake; slim and duller black in the North American Racer. The indigo is slow and deliberate; the racer fast. The scale before the vent is single in the indigo, divided in the racer.
