Avengers: Endgame new clip has Black Widow trying to find Thanos, but her changing hair colour leaves us perplexed

Avengers: Endgame makers are piquing the curiosity for the film by dropping a new clip everyday based around the film. On Thursday, Marvel Studios dropped another teaser focussed around Black Widow played by Scarlett Johannson. In the short video, we can see Black Widow trying to find a way to Thanos in a 3-D projected globe. But it's her changing hair colour that has left us confused. In some of the sequences, Natasha Romanov aka Black Widow is spotted in ombre haircolour while in other, she's perfectly blonde with hair cut short. This minor detail has also raised speculations about possible theory of time travel in Avengers: Endgame. It might be possible that the remaining Avengers will go back into the time with the help of Ant-Man to undo the damage Thanos did in Infinity War.
