It is not the first time that a Manchester United kit combines two shades of red. For the last time, this had been the case in the 2016-17 season.
For the past two seasons, Adidas has used black as the accent color for Manchester United's home kit.
Template-wise, the Adidas Manchester United 24-25 home shirt is based on the new Tiro 24 template, but probably with some adjustments to the collar.
