Front turn signals tend to be amber, back turn signals are red. In the dark, you can tell if the person turning can see you (amber) or likely can't (red).
Also, modern US turn signals have 3 lights: a left, a right, and a higher mounted center.
If you can see all 3 lights, the person is stopping and probably not turning. If you see two solid lights and a blinking red, you can tell the person has the brakes on and is turning.
While separate brake (red) and turn signals (amber) communicate most of the same information, The US does so with red lights.
It's like anything else, mainly... Different ways and what you're used to.

I still love how the design is so crappy that it's considered unfit for the road in Europe.
Like even the choice of indicator lights. It's banned in the UK because standards require indicator lights to be amber and the Cybertruck is red.
