The comics as they originally appeared in "Eightball" employed only two colors; the early chapters were in black and dark blue, then black and a lighter shade of blue later on, and black and light green for the final two chapters. The graphic novel reprint uses this light green and black color scheme throughout. There is one inadvertent exception: in "Eightball" #16, a printing error led to the entire chapter being published in an orange tone instead of a blue one. "No one quite knows how or why this happened," wrote Clowes in "The Complete Eightball," a 2015 compilation of the comic that faithfully reproduces the mistake.
