/**
 * Module that assigns each particle a random color.
 *
 * Color range can be customized to some degree using `palette` property.
 *
 * It is a array of Colors. Any interpolated step between the colors in this array can be assigned to particles.
 * For example, the following configuration results in particles varying from Red to Green colors:
 *
 * ```ts
 *  const color = new RandomColor(effect)
 *  color.palette = [
 *      { r: 1, g: 0, b: 0 },
 *      { r: 0, g: 1, b: 0 }
 *  ]
 * ```
 *
 * Color interpolation can be disabled by setting `interpolate` to `false`.
 *
 * @module
 * @category    Initializer
 * palette {
 *      @tooltip        TODO
 *      @type           Color[]
 *      @defaultValue   [{ "r": 1, "g": 0, "b": 0 }, { "r": 0, "g": 1, "b": 0 }, { "r": 0, "g": 0, "b": 1 }]
 * }
 * interpolate {
 *      @tooltip        TODO
 *      @type           Boolean
 *      @defaultValue   true
