Decisions made.
Starting left to right, base layers are: white, grey, silver. I am going with door number 2. It gives me the red/orange I am looking for. The top layer is MRP International Orange.
Starting left to right the base layers are white, white, and silver. The top layers are Haze Grey, Dark Camouflage Grey, and Gunship Grey.
If you'd asked me what I was leaning towards before todays test I would have said, Gunship Grey. Before all that, I would have said Dark Camouflage Grey.
As you know, I reviewed a bunch of images. In my opinion, none of them are definitive. Screencaps of the show are woefully unreliable. Heck... one of them has the Jupiter 2 looking tan. Can I trust the same image where the Chariot looks silver? Nope.
This leaves the 1:1 images. The builder states accuracy was at the forefront of the build, right down to the switches. I'd imagine then that something as important as color had been heavily researched. I must go on that assumption. But, reviewing 1:1 images has me wanting as well. Virtually... every image have marked differences in hue. Various light sources and an improperly calibrated camera can account for this. That said, from my experience, and in terms of color temperature, cameras balance easier to sunlight. And this is why I chose the two images below for my reference photos.
And this is why I am going with door #2, Dark Camouflaged Grey.
Much ado about nothing but doing a little research can go a long way towards the fun and realism of the build.
Right or wrong... it's my best guess for color.
PS: Each time I use MRP lacquer I am blown away. What a joy to spray with. Take out the toxicity of lacquer, it becomes the perfect paint to airbrush with.
