Yikes!  Mind if I say that this is really bad?  :-)
The problem is the mixture of yellow and blue going on all over inside that
flame.  You'll need to do a density_map method which separates the parts
out, perhaps using a gradient y pattern for the overall spread of the
density parts from bottom to top, with each of the contributing densities
being patterns of their own.  Example:

 #declare D1=
density {wrinkles density_map {[0 rgb <1,.5,0>][1 rgb <.5,.25,0>]}
sine_wave}
 #declare D2=
density {wrinkles density_map {[0 rgb <1,1,0>][1 rgb <.5,.5,0>]} sine_wave}
 #declare D3=
density {wrinkles density_map {[0 rgb <0,0,0>][1 rgb <0,0,1>]} sine_wave}

 density {gradient y density_map {
  [0 D1] [.5 D2] [1 D3]
 }}

Not of any help doing this in Moray, sorry. Maybe it will show what I mean
though.  Finally put the complete thing into it's spherical shape.
