Four Angels on a Tree Puzzle

March 29

There were four angels on a Christmas tree. Two had a blue halo and two yellow. The angels knew that; they just did not know who had which color. None of them can see their own halo. Angel A is on the highest place, and he can see angels B and C, which hang below him. Below hangs angel B, who can see only angel C under him. Angel C can't see anybody. Angel D can see no one, and no angel can see him.

Which one of them can announce what color his own halo is? See tomorrow for answer.
