      Parameters:
      rgb - range 255 255 255
      doRound - set to false when just using this for for RGB -- HSL -- HSL' -- RGB' conversion
      Returns:
      the HSL as P3 range 360 100 100

    • hslToRGB

      public static P3 hslToRGB(P3 hsl)
      Convert HSL (hue/saturation/luninance) values to RGB
      Parameters:
      hsl - in the range 360, 100, 100
      Returns:
