Inherits: EffectBase

Palette-cycling diagonal rainbow effect, and the default the tests reach for.

Author: FastLED rainbow (Mark Kriegsman), via the predecessor, https://github.com/ewowi/MoonLight/blob/main/src/MoonLight/Nodes/Effects/E_FastLED.h

A pixel's hue comes from its own x plus y, walked by the clock, so the bands run diagonally.

Public Attributes

uint8_t speed = 20 : How fast the rainbow cycles, where a whole one a second reads too fast.

Public Methods

virtual inline Dim dimensions() const override : Writes the z=0 slice, which extrude duplicates through a volume.
