I'm intrigued. The sets of numbers that pop up when mousing over the bottom half of the ring seem to be the only clue.
They are (in order):
0.0.F.F.C.F
F.F.0.0.D.0
8.E.0.1.F.F
D.A.F.F.0.0
F.F.0.1.0.1
0.1.D.4.F.F
0.0.0.B.F.F
4.2.F.F.0.0
F.E.A.7.0.2
They obviously seem to be hexadecimal numbers. The dots would indicate they are not group in pairs, but the numbers themselves suggest pairing as such:
00 FF CF FF 00 D0 8E 01 FF DA FF 00 FF 01 01 01 D4 FF 00 0B FF 42 FF 00 FE A7 02
But what does that mean? The numbers exceed the standard ASCII values. They could correspond to colors as they do seem to be grouped into 3 pairings, the same way you would signify a color using 24-bit color depth, but then you just have colors and what could that mean?
FF, 00, 01 seem the most prevalent. Perhaps syntax of a sort?
