Just a quick one today, as I try to force myself out of the painting doldrums ( I should have posted this on May the Fourth, of course). I got a rather nice Millennium Falcon for X-Wing, and note that the otherwise good paintjob is let down by the absence of the sublight engine glow. The TIEs and X-Wings themselves, you don't really miss it, but on this big ship it is somewhat conspicuous in its absence.
I did some research:
I had it in my head that the engines give off a blue glow (like the box art), but the film clearly shows predominantly white (except when escaping Tatooine). Maybe there's a faint blue tinge around the edges if you don't quite look at it directly...
Anyway, I decided to go with simple, and a few thin coats of white later:
I had been thinking of leaving it there, but already I am thinking of adding a tinge of blue- here's a nice one from Martin at the Fire Broadside blog:
