In track rows in PDB files, the color ID field is just a single byte (cid at offset 0x58). The same goes for the color index in Extended (nxs2) Cue List entries of analysis files (cid at offset 0x1c).
But for PDB color rows, the documentation states that the field is 2 bytes large (id at offset 0x05). Is there a reason to believe that this field is not just also a single byte, and the second byte belongs to u3 or is yet another unknown byte field?
