>dressed the same as him
It's a suit, a very common outfit for when you want to show that a character is a normal but somewhat professional adult man.
>same hair color
Ok, but black hair is easily the standard when it comes to Japanese fictional characters unless it's a setting with neon hairs (which as far as I can tell, neither of these two are). Black hair is just the default in nip media, especially for men since their hair isn't as much of a focus as for women. It's no surprise when essentially all nips have black hair.
The appearance similarities honestly just seem like like a coincidence as it's very much a default, working man look. Maybe he was an inspiration, but I'd be willing to assume that it's a coincidence.

That's some YMCA shit right there.
