plrgbhls - Convert RGB color to HLS

r (PLFLT(3plplot), input)
              Red intensity (0.0-1.0) of the color.

       g (PLFLT(3plplot), input)
              Green intensity (0.0-1.0) of the color.

       b (PLFLT(3plplot), input)
              Blue intensity (0.0-1.0) of the color.

       p_h (PLFLT_NC_SCALAR(3plplot), output)
              Returned value of the hue in degrees (0.0-360.0) on the color cylinder.

       p_l (PLFLT_NC_SCALAR(3plplot), output)
              Returned  value  of  the  lightness  expressed  as  a  fraction (0.0-1.0) of the axis of the color
              cylinder.

       p_s (PLFLT_NC_SCALAR(3plplot), output)
              Returned value of the saturation expressed as a fraction (0.0-1.0) of  the  radius  of  the  color
              cylinder.
