I went more for my interpretation of what it looked like on screen. The "Real" colors were an light grey-green, an even lighter grey-green and then the horrid light grey-violet color... based on color corrected pictures of the shooting miniature. I never really liked the school of thought that said "make it look like the 'real' model, I still like to try and duplicate how they looked on screen. or even my own what if color scheme. Your colors are just as valid as mine, in your universe. Your mileage may vary.
