since this is art, it's a matter trial, patience and phantasy. I would try
(I shortly did, but lack the patience) something like, e.g.

ParametricPlot3D[{Sin[u]*Cos[v], Cos[u]*Cos[v], 
      Sin[2v], {EdgeForm[], Hue[=some function of v=]}}, {u, -Pi*3/4, 
      Pi*3/4}, {v, -Pi/2, Pi/2}, Axes -> False, Boxed -> False, 
    Background -> GrayLevel[0], Lighting -> False, 
    PlotPoints -> 100] // Timing

To reverse engineneer that =some function of v= (or of u or both), observe
how u varies along the polygons, try to guess the argument to Hue (best make
a plot), find the most "simple" function that approximately matches your
guesses, then fine tune the parameters by visual appearance. The art is not
to spend (or perhaps just to spend) a lifetime.

For guesses of a "simple" function follow the complexity of the function
itself, for the example here try simple algebraic expressions of v, Sin[v],
Hue[1/3 - Sin[v^2]^2] just isn't it (it lacks certain obvious properties),
but may explain that approach.
