 * one color, or limit is less than 2, then this defaults to DawnBringer's Aurora palette with 256 hand-chosen
 * colors (including transparent).
 *
 * @param colorPalette an array of Color objects; all will be used up to 256 items, limit, or the length of the array
 * @param limit        a limit on how many Color items to use from colorPalette; useful if colorPalette is from an Array
