This is a companion piece to https://www.fxhash.xyz/generative/3831 - Moiré_Ellipses_Light. There's little difference between the two aside from palette choice, and variation is somewhat limited.

Between four and six elliptical rings rotate in alternately contrary directions. Each ellipse is bounded within by a further ellipse, and between these two points, striations are marked at a slight angle. The resulting motion produces emergent Moiré patterns.

The number of ellipses, their segmentation level and colour are all generated from hash. The eccentricity of the inner and outer ellipses is also hash-generated, resulting in uniquely beautiful images.

This version features lighter hues and a darker background.
