Thr are two possibilities but only if the angels have sufficient intelligence and faith in each others intelligence.If B & C have identical aurioles i.e. 2 yellow and 2 blue then A will speak out first cause he can see them and can deduce.Otherwise A will remain silent so B will realise that he and C must have different coloured aurioles or halos else A would have spoken.So B will look at C's halo and can then deduce the colour of his own.(No colour isn't spelled wrong,its British spelling)

This doesn't make sense. If Angel B can't see Angel A, how does Angel B know that Angel A can see Angel B and Angel C. Why wouldn't Angel B just assume that Angel A is behind a twig like Angel D? There is no reason that Angel B should think that Angel B's color is different than Angel A from Angel A's silence. The first answer (if Angel B and Angel C are the same color) is obvious.

Exactly what I was thinking. How would B know that A can see B and C since B can't see A at all?

Well LOGIC would tell me that the angels on the christmas tree are inanimate objects, therefore cannot guess, deduce colors, or even think....EVER

An additional assumption that must be included when telling this brain teaser is that the Angels know which Angels can see eachother. It is a key stipulation.

In the last line of the riddle, it asks for the first angel to have a GUESS. so the answer from the angel does not have to be right, therefore i think while angels A,B and C are thinking, angel D would have simply guessed straight away as there would be no way for him to tell what the other angels were wearing, so he would simply not waste time achieving nothing :D

that "guess" thing was picked up and edited long time ago to the following:
Which one of them will be the first to guess (Edit: speak his guess out load, deduce and say) what his own aureole is?

well assuming angel b and c have the same color, angel a can conclude he has a color other than theirs,
then angel d would be safe to say he is the same color of angel a, and b can say he is same of angel c :rolleyes:
