    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()


    darkerMagenta = magenta.lightness(0.75)

    # to see what they look like
    for color, index in ['yellow', 'gray']
      canvas.drawRect
        color: eval(color)
        x: 20 + (60 * index)
        y: 20 + (60 * index)
        width: 60
        height: 60 
    </pre></code>
