Default Diff between Injectors

So when looking at the parts catalog, I see black, green, yellow and brown orings around the connector.

What is the diff between the two for the DI injectors?

I need to know which two to purchase?

I can't find anything in the documentation explaining or even mentioning this. It sounds important, but without any word from Lexus, it's hard to say what it means or if it is actually something important.

Do you know of any master tech or any other way to find out? I agree sounds important, maybe it's a flow matching system or some sorts.
