This shouldn't be called "Infinite hats", since being able to specify whether there are an even or odd number of red hats ahead of you relies on that number being finite.

How about "Arbitrarily large but finite Hats"

A more fool proof solution would be to have a strategy in which each person will call out the color of the hat of the person who is immedietly in front of him/her. That way, except for the last person in the line (I mean, the one who dont have anyone standing behind him/her) every one will be able to tell the color of their hat.

you're wrong: they can only tell a hat color, and thus they will tell the person in front of them, but not theirs. Thus the only persons who will correctly tell their hat's color will be the ones that have hats the same color as the person in front of them!

And also 'arbritrary large' is not true: the time needed to count the hats, and then to tell something, and then for the next person to do the same takes time, and we can assume 'people' means humans, and thus the limit is quite low.

And the planet's curvature comes into play too... they can't see too far.

People's sight accuracy are a limit too...

They call the hat colour of the person in front of them, then everyone but the first person knows their own colour and is able to say it accurately.
