Color scheme optimization. For the sake of clearness the color space was constrained to a single lightness value of L* = 60. Otherwise the shown results use the default parameters of the CLI invocation. a The score trajectory is plotted against the number of optimization steps. For clarity only every 100th step is displayed. b The plot shows the final color conformation after optimization. The white area displays the allowed color space. The position of a symbol depicts its a* and b* value
