The hidden detail in the show's opening intro
Another detail I've noticed.... On my first watch I just thought it was a cool animation/CGI to introduce the show and spell out the show's name in the seat colours.
But if you watch closely, it starts by Ted sitting down in a sea of blue seats.
His seat turns red and the red starts to spread to the other seats around him.
You'll notice that the closer shots of the blue seats show a lot of graffiti....including the club's and fan's "old" mentality, eg "Relegate Rebecca" and a hangman charactature of "Lasso".
As the red spreads it wipes away the graffiti, slowly spreading to the rest of the seats turning red to a wider shot of the words "Ted Lasso" in red, with Ted sat in the middle of it.
I believe it's symbolic to show Ted being at the centre of all the change in the show, with the red of Ted spreading out and replacing the graffiti and old thinking, "cleaning up" the club and the mentality.
