     @name lightness

    A getter / setter for the lightness value of the color. Passing no argument returns the 
    current lightness value. Passing a value will set the lightness to that value and return the color.

    <code><pre>
    magenta = Color(255, 0, 255)

    magenta.lightness()

    <code class="run"><pre>
    magenta = Color(255, 0, 255)

    magenta.hue()
    # => 300

    # modifies the color to be yellow
    magenta.hue(60)
