Can you only answer Red or Green in Common or can you use other languages? If so, Red in common means that yours is red and the person in front of you is red as well. If you say red in Gnomish, yours is red but the person in front of you is green.

Adventurer 1 takes a look ahead and seed 9 flames ahead of him. If there are an even amount of red flames, he says red. If there are an odd amount, he says green.
Adventurer 2 looks ahead. If adventurer 1 said red, indicating an even amount, and 2 sees an odd amount, he knows that his flame is red.
Adventurer 3 looks ahead. If 1 said red, 2 said red, he now knows there are an odd amount of red flames left. If he sees an even amount, he knows he is red. Do I need to explain this further?
interwyrm said:Technically... that last question would also work if you called out whichever color you saw more of...
