Identify Jumps and Cuts

Branch cuts and jump discontinuities can result in plots that have sharp transitions from one color to another due to not being continuous in a region.

has a branch cut resulting in a sudden jump in the color gradient along the negative real axis. The color spectrum goes around the zero at the origin 1.5 times.

A fractional pole shows a similar jump in the color gradient while proceeding clockwise instead of counterclockwise.

Floor[z] is constant over regions of the complex plane, with sharp jumps from region to region.
