But the teammates make the adjustment as smooth as possible.
The Chelsea defender’s loan was one of the stories of the window.
He is yet to start but has come on as a substitute to secure narrow victories over Manchester United and Leeds.
He also came through a full game in the Carabao Cup win over Forest Green.
Colwill, 19, caught the eye at Huddersfield last season and has now taken it up a notch.
He said: “I think that’s the quickest thing I’ve settled into because of the players, the gaffer and everyone at the club.
“They helped me settle in with the boys.
“I feel good among the boys and I’m ready to play football.”
Colwill showed a strong and mature performance in the cup game at Forest Green alongside Jan Paul van Hecke and Ed Turns.
Goalkeeper and skipper Jason Steele was particularly impressed by the composure displayed by the youngsters in front of him as the League One side pressed on.
Colwill said: “It was similar to a league game but I really enjoyed it.
“It was good to get minutes, good to get fit again.
“Of course I’m not there from preseason, but I’ve been working hard every day.”
Colwill’s summer schedule was delayed by the fact that he reached the championship playoff final.
When asked if he had a disjointed preseason, he said: “It wasn’t very fitting here, I’d say.
“But I’m slowly reaching the level and standards of the team. “The training is very different for every team you go to.
“I pick up little things here and there, which helps me a lot.
“I just have to keep learning”
Colwill has occasionally trained with older players at Chelsea.
But his day-to-day work is perhaps best compared to what he did at the top end of the championship last season.
The 19-year-old said his day-to-day work with the Seagulls feels like a big step up.
He said: “There are better players.
“Everyone on the team is such a good player.
“I have to get better and move up.
“It’s a big leap to be with them every day and train with them.
“The standards are higher, you can’t let them fall.”
Colwill praises how he’s settled in with his new colleagues.
He said: “I can’t say one bad word about a person.
“Everyone helped me, especially the other defenders.
“If I want to ask someone, I feel comfortable enough to go to them and they just help me with everything.”
It all led to those opening minutes at the Amex thrown into the heat of battle as Leeds struggled to get back on terms.
Colwill responded and put in a solid, uncomplicated job at left-back.
He said: “It was a good time to progress and win.
“You have to go through with it, you can’t make any mistakes.
“But I really enjoyed it. The fans have been brilliant.”
Steele is among those who had trouble believing Colwill was still a teenager.
When asked how that maturity has manifested from both Colwill and van Hecke at Forest Green, Steele said, “They’re just very calm and comfortable out there.
“You can see that in the last 20 minutes where we have to break in a bit and they have a lot of territory, you never despair.
“Nothing is desperate. It’s very calm and that’s the mark of a good player – staying calm in difficult times and handling situations.”
