I'm not sure if flames like those are possible. The yellow, orange and red
colors in flames are caused by hot particles that glow. And the blue light
in flames is the light that is caused by the chemical reaction that we call
"fire". A perfect flame is blue. So if the inside of the flames are red,
were are the particles going more in the "back" of the flame? if they stay
(which should be the case in a hot, blue flame) they'll have to continue
glowing. And if they cool down they're supposed to become dark but still be
visible.
What kind of media did you use inside those spheres? Any density variation?
