6: About Color Map
…
►Surface visualizations in the DLMF represent functions of the form by the height or the magnitude, , for complex functions, over the plane.
…
►In doing this, however, we would like to place the mathematically significant phase values, specifically the multiples of correponding to the real and imaginary axes, at more immediately recognizable colors.
…
►We therefore use a piecewise linear mapping as illustrated below, that takes phase to red, to yellow, to cyan and to blue.
