This is the gamma function Γ in logarithmic complex-color (red is 1, chartreuse is i, cyan is -1, and indigo is -i) on the complex plane with circles of radius 1 through 10 drawn as dashed lines about the origin (with z=1 located rightward of center and z=i located above center). Increasingly narrow singularities are located at integer locations along the negative real axis, which alternates from negative to positive to negative between poles at 0, -1, -2, and -3, etc. The "white out" regions of each pole are more easily seen in a zoomed-in linear complex-color version of this figure.
