I'm pretty sure that whatever way this goes, the answer has to be "A"

It depends on which angels have which color. If B and C are either both blue or both yellow, then A will instantly say "I am (insert other color here)." If B and C are different colors, then A will not say anything. In this instance, B will say to herself "A doesn't know what she is, so C and I are different colors, and since C is x, I am y." D just uses up the second of whatever color isn't used twice in the above angels.

B will be the winner and his color would be Blue (or Yellow) if C's halo is Yellow (or Blue). The logic goes like this:
1. A (top MOst): Can see everyone's halos except Ds: He can answer only if B and C have same colors. Fore.g. if B and C have Yellow then he will know he and D have Blue color halos. But in case B and C have different color halos, A can't be sure whether he has Blue or Yellow.

2. B knows taht A has now shouted the answer, so B's and C's halos are not of same colors. They have to be different for A to not to should out the answer. So B has to just look down for C's color. If C is Blue,then B is Yellow, else vice versa.

So B is the winner.

The wording should be changed to say that the Angels actually speak their guess out loud. I read "guess" as "silently figuring it out" because "guess" is an internal thought process, at which point I concluded that A was the only one with any hope of figuring out his own color and only when B&C have the same colors as each other.

So, when a guess IS possible, it's only A that can do it... unless the wording is changed.


Not completely true. If A saw that B and C had the same color, A would immediately know that it's color was the other one. If A saw that B and C had different colors, A would not be able to make a guess. When A didn't speak, B would realize that A did not know, and therefore B would know that B and C must have different colors. Knowing that it's color was not the same as C, B would be able to determine that it's color had to be the other one.

So if B and C's colors were the same, A would be able to guess. If A could not guess, B would know it's color was the other color from whatever color C is.
