[image=http://i1143.photobucket.com/albums/n637/Bushy162/Screenshot2011-10-21at212647.png] Here's mine, applied to the previous frame, before ignition.

Basically, I've used a combo of colour balance applied to blurred white solids, AND actual blue solids. Darken and Darker Colour were used for the orangey bit in the core, and I also got the blue just outside the core taken away using Darken again. Blur sequence was a bit flakey, but I'll get to that later.
