Here's what I did (I keep notes on all my painting)
Yellow Vorlons:
White Primer
Vallejo Sunblast Yellow 72006
Stipple Vallejo Cold Grey 72050
Light Stipple of Sunblast Yellow and Vallejo Bold Moon Yellow 72005 for effect
Red Vorlons:
White Primer
Vallejo Scar Red 72012
Stipple Black
Light Stipple Scar Red and Vallejo Bloody Red 72010 for Effect
"Underwing "Blue of the Transports
Vallejo Magic Blue 72021
Stipple Black
Light Stipple of Black and Magic Blue mix
I assume you know what stipple means, but just in case, it's stabbing with a firm brush so you get pokes instead of strokes.
For insignia
Americana Neutral Gray
Stipple American Grey Skey
Edges Vallejo Ghost Grey 72046
Vallejo Bloody Red 72010 over white for insignia itself
Exhausts
White
Partha Flourescent Yellow (this is hard to find, but any flourescent yellow will do - it just needs to glow more than the surrounding yellow which is pretty bright).
