What actually are the colors of afterburners(flames)?

Are they blue? or are they red/orange?

Just wondering.

Well, most people think that afterburners (AB), which are also known as "reheat" (as in 're-heat' the exhaust) only glow red. In reality the same engine, same day, can appear several colors, such as white/blue (especially in the dark), orange edges with clear or yellow center. Obviously, temperature affects the colors, and external lighting conditions also seem (at least to me) to play a part.

Some times you can't even see the burners at all unless you actually look INSIDE the tailpipes after it passes you. I think that Janes F-18 tries to model these multiple colors, but I figure they got the shape wrong even though I'm a grunt by trade!

Basically white or blue color indicates that at that part of the flame there are is only gaseous matter present, if it's orange/red it means there's solid carbon particles in the flames that emit.

Would the type of fuel (JP-5/JP-8 and stuff) have something to do also?

Thanks

Well, when you are a kid and participate in light&fart contests everything depends on the contents of your most recent meal...

Our F-15's run the P&W -100's and look orange in the daytime and a white/blue at night.

I've seen the F-16's that use the GE motors, look ornage in the day and really blue at night. Hmm, go figure.
