Junior Number Theory

A graph with curved lines and a spectrum of color in the background. Because graphs of complex-valued functions naïvely require four dimensions to display, they can be very difficult to visualize. Domain coloring works around this by representing two dimensions as colors: given a function f, color the point (x, y) using the value of f(x + iy). The hue represents the argument of f(x + iy), and the luminosity varies periodically with the magnitude to produce a terraced effect.
