LOL I don't think I've ever seen white rays.
Gray rays are pretty ambiguous, and I don't think you can discern anything from them other than that they are not black nor blue. I know I looked into them once a long time ago and found that they are not necessarily reciprocal. IE a ray can be gray going from region 1 to region 2, but from region 2 to 1 it's brown.
