Domain coloring is a technique for visualizing functions of a complex variable. The term "domain coloring"
was coined by Frank Farris possibly around 1998.[1][2] There were many earlier uses of color to visualize
complex functions, typically mapping argument (phase) to hue.[3] 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
[4] and colored grids were used in graphics by Doug Arnold that he dates to 1997
