The value ranges are mentioned in FromHSV() of Color3:

Original code:

          private static _BlackReadOnly = Color3.Black() as DeepImmutable<Color3>;

          

          /**

           * Converts Hue, saturation and value to a Color3 (RGB)

           * @param hue defines the hue

           * @param saturation defines the saturation

           * @param value defines the value

           * @param result defines the Color3 where to store the RGB values

           */

          public static HSVtoRGBToRef(hue: number, saturation: number, value: number, result: Color3) {

              const chroma = value * saturation;

              const h = hue / 60;

              const x = chroma * (1 - Math.abs((h % 2) - 1));

              let r = 0;

              let g = 0;

              let b = 0;

          

              if (h >= 0 && h <= 1) {

                  r = chroma;

                  g = x;
