Domain coloring is a technique for visualizing functions of a complex variable. The term "domain coloring" was coined by Frank Farris possibly around 1998. There were many earlier uses of color to visualize complex functions, typically mapping argument (phase) to hue. The technique of using continuous color to map points from domain to codomain or image plane was used in 1999 by George Abdo and Paul Godfrey and colored grids were used in graphics by Doug Arnold that he dates to 1997.
