Does that really say DARK OLIVE & MED BLU?

Ad says truck originally green, po painted over with white/yellow. No worries, but the SPID floored me. Unless, of course, my eyes are playing tricks on me. The code is hard to read, but looks like 556, which is a dk olive over med olive RPO. But the wording sure looks like BLU to me... Misprint perhaps. Who knows. I see no trace of blue. Anyway, interesting.
