Marvel theory time

I read a theory that Natasha kept her hair red when she lost her Bucky so he could find her. In infinity war, when they knew where Bucky was, her hair was blonde. The pics from avengers 4 show red hair again. She’s lost her Bucky again. It’s an interesting observation. Of course, they haven’t shown any Bucky Nat in the MCU but it’s Canon in the comics.
