I appreciate the explanation, however this is not entirely true in my case. The lighting kit for my trackball does not have a dedicated white LED. I even purchased a 2nd identical one and once installed, it produced the same results. I also installed 2 RGB illuminated joystick handles, and they produce a color closer to white than all my other RGB's. I've attached 2 photos showing how white the trackball used to be, and what it currently is. I've reached out to Andy at Ultimarc, however he didn't really have an explanation other than it could be software related.
