Color.x is just a hack used by those who have been RTTL :) If you have
Color.r and Color.hue, why use Color.x and make your life harder? Of
course, for backwards compatibility it should be kept equivalent to
Color.r

Another approach is to use rgb space and automatically convert hsb to
it. So color hsb <2/3,1,1> would make a color rgb <0,0,1>. One may
still access the hsb values of this color, though.
