Talk:Signal flare

Where are the rest of the citations?
I edited this article and I put several references. However, there are some of them that I could not find. Finding the purpose of the green, red and black flare is easy. But what about the blue or the purple flare, for example? Do you know where I can find them? Thank you :) Raposu (talk) 13:51, June 5, 2015 (UTC)Raposu
