Addresses already in Address Book display in red in the TO field
When typing the start of a name (address) in any of TO, CC or BCC fields, names already in the Address Book, Thunderbird suggests options as usual but once a name is selected, it sometimes displays in red, sometimes in black, and sometimes start off in red and when I click on the one I want or press enter it ends up displaying in black.

The red lettering does not cause any sending issue.
