Why does the color code in tray cable start off Black, Red, Blue, instead of at least having a green in it?

Care to expand on your statement, or clearify what Article your stating this from.
I read through the first three pages of NFPA 72 - 08'(I didn't follow every code reference of Table 392.3(A))
of Article 392 Cable Trays and misssed the open lines on color ?
