The color of an HID is determined on a x,y axis. However this axis isn't just 1 quardrant. Instead its like a circle w/ the poing 0.0 as the center. As you move around the circle u start to change color. Here's the thing, Just because K rating goes up doesn't mean u induce more blue/purple. I've seen 7000k bulbs are are just blue w/ no traces of purple, and then again i've seen 7000k bulbs w/ just purple w/ no traces of blue. After you get the x,y axis correct, then there's a z axis that determines light output. It's a really strange new concept, but it seems to explain lighting better than the normal x,y graph on just 1 quadrant.
