I think that after completing BOW, I was never too green to dive without a DM or instructor.
But this was a matter of picking the right dives--kind of what NWGratefulDiver said, it depends on the environment. As a new diver, I was usually well-calibrated, picking dives that were shallow, low current, etcetera.
The dive that I was "too green for" looked easy: 15 feet deep, slight current. But what I didn't think through was the combination of shallow depth, poor visibility, some boat traffic, and not-fine-tuned buoyancy control. During the dive, I started to float up a bit and in the poor visibility, immediately lost any visual reference for depth. I tried to dump air from my BC, but I was slightly head down. By the time I dumped the air, I was already on the surface. Luckily, there were no boats passing at that moment.
So although I was not to green to dive independently of an instructor, I was too green to judge the challenge of that dive correctly. So too green in this case meant, "didn't know what I didn't know."
