A closet has 3 blue and 2 red hats.  Elvis and two of his roadies go into a closet and each selects a hat at random in the dark and places it on their head.

 

Once outside the closet, each man is unable to tell what color their own hat is.

 

The first man looks at the others and says "I cannot tell what color my hat is!".

 

The second hears this, looks at the other two and declares "I cannot tell what color my hat is either!". 

 

Elvis, who cannot see colors with his super-dark sunglasses, confidently declares "I know exactly what color mine is!".

What color is Elvis’s hat?
