Yes, right tail light does flash with right turn signal on. As I went down your list of things to check, I found what appears to be a loose connection in the curved connector for the steering column. Upon wiggling the connector the right turn signal starts to flash and things are normal. I'll check what's up with the dark blue wire. Thanks a bunch for the troubleshoot. At least I won't have to tear the steering column apart and replace the entire switch. Thanks again!
