Most likely not. You had to have gotten the Bungie app by the 7th of some month. So unless 343 Industries does the same type of thing, no.
Forever if you have them
You cant any more:(
You can get the blue flames on Halo:Reach by downloading the app on an iPod touch, iPhone or iPad, or you can ask a friend if you don't have one. When you have the app sign in to it using your bungie live ID then you can unlock the blue flames.
if you want the blue flame sign in at bungie.net and subscribe bungie pro. but know if you have a iphone/ipodtouch you can turn on blue flames and it will pop up in armor effect. but if you want normal flames buy legendary edition of halo reach.
rookie blue does not exist i guess.
You could have gone on Bungie.net on July 7, 2011, but they don't give them out anymore.
I have heard rumors that he is coming back late in the season but I'm not sure
Hi, Blue plasters are used for hygine reasons. Blue is a very prominent colour as not many (possibly no) food is Blue So, it should be easy to spot
Green flames are typically not as hot as blue flames, but are hotter than red or orange flames.
blue
The two main types of flames are blue flames and yellow flames. Blue flames indicate clean, efficient combustion with sufficient oxygen, while yellow flames indicate incomplete combustion with impurities present.
Flames can appear blue when they burn very hot. The blue color is due to the presence of carbon and hydrogen molecules in the flame that emit blue light when they are heated to high temperatures.
