A transaction that I recently sent from one wallet to another shows up in Armory highlighted red and with a comment that says "***MEMPOOL REPLACEABLE***"
All other transactions are the regular color.

Does anyone know what this is about? The red highlighting and full caps warning is alarming.

That means that the transaction could be replaced in the future and thus be dropped from the mempool and never confirmed. This means that it either opts into RBF or it is part of a chain of unconfirmed transactions.
