Sets the color described by the ImagickPixel object using normalized values for hue, saturation and luminosity.

hue: The normalized value for hue, described as a fractional arc (between 0 and 1) of the hue circle, where the zero value is red.
saturation: The normalized value for saturation, with 1 as full saturation.
luminosity: The normalized value for luminosity, on a scale from black at 0 to white at 1, with the full HS value at 0.5 luminosity.

Returns TRUE on success.
