-It looks similar. sawtooth-shaped lightness profile made up of 6 ramps ( segments)
 
 Features of rainbow gradient:
-* non monotone ( see black curve) , cyclic, multi hue
+* non monotone ( see black curve) , 
+* cyclic
+* multi hue
 * complex = consist of 6 monotone segments ( ramps). Graph of the lightness looks like [saw with plain tooth pattern](https://en.wikipedia.org/wiki/Crosscut_saw) or [triangle sawtooth wave](https://en.wikipedia.org/wiki/Sawtooth_wave)
