I have seen one of the best looking blue, it is likely to use a hexamine, who knows the formula can tell me

That is by far the best blue I've seen. Even the green is much different from what you usually see but it reminds me of a shell someone told used Barium Perchlorate. I never got to try it though. If I remember correctly it's super expensive. No guesses for the blue. Looks nice though.
