But outgoing messages are blue. Yes, I have checked my iMessage settings. Yes, the receiver is an Apple user. Yes, my phone has the latest update. Yes, the SMS is on. What am I missing???

That is correct their message is white/grey, there is no issue with your imessage.

Only the outgoing messages are blue/green. Not the incoming messages.
