Costuming on Ted Lasso

We know that music played an integral part in the series. And I'm sure this has been discussed here at some point, but costuming also was a very conscious choice. From Mrs. Higgins' blue outfit in ""Rainbow" to Trent's increasingly casual garb through the series showing him loosening up and becoming more approachable through the three seasons, the story is reinforced by style choices. I particularly like Nate and Rupert's arcs: Nate as he becomes antagonist (and his clothing choices reflect that); Rupert, who we are first introduced to in a white tuxedo eventually gets to a "Dark Neo" look in the series finale, looking every bit the supervillain.

One thing I believe I saw referenced here once but I would like to revisit: Nate's hair. From pitch black when we meet him in the series opener to grey/white by the series end. This couldn't have been just aging, as we only see him through three seasons/years. Was this ever officially acknowledged as being another example of showing a character's development? Also, am I missing any other examples?
