    A good example of where this is used, is RGB charts. Red Green Blue.
    FF0000 = Red The first two digits being read
    FFFF00 = Orange and yellow A mixture of red and green
    00FF00 = Green Second digits being green
    00FFFF = Cyan A mixture of green and blue
    0000FF = Blue The last two digits
    FF00FF = Purple A mixture of red and blue
    So that's what controls the hue, and these just control the saturation.
