Once you see a Moody Blue you'll never mistake it again, the base is a tad muddy looking in you first OP but not nearly enough to be considered muddy, in hand is sooo much better for learning, still both Pelt Rainbos IMO
Both Rainbo's IMO, Moody Blue is on a muddy base, yours appears to be translucent & Rainbo type instead of NLR ribbon type, I wish I had better news for ya.
