Forgive my ignorance, but what is the point of the different colored marks on fuel injectors? I'm looking at two identical injectors from the same company, but the green colored mark is more expensive than the orange colored mark.

Why?

Apparently, the dots on OEM injectors have something to do with spray patterns. In practice, it seems to mean nothing.

On aftermarket injectors, it could mean anything.

Ok. I'll just go with the OEM injectors then.
