because spy 4 cannot tell the color on his own hat, that implies spy 2 and 3 has different color. spy 3 would be able to come with this conclusion. then spy 3 also knows spy 2's hat color. that means, spy 3 is the person to know his hat's color
Yes spy 4 can see spy 2.... therefore spy3 knows the color of his hat.
So you are correct 250.
