I built the MG 1/100 Gundam Barbatos Lupus.
I was planning to paint it in low-visibility colors when I had the idea to paint the left shoulder orange to give it a prototype look. Since the Iron-Blooded Orphans world seems to have kanji characters, I used kanji decals. The Tekkadan mark on the shoulder was filled in with putty to represent the prototype.
Gray: Mr. Color C308
Blue: Gaia Notes Hexa Blue
Silver: Tamiya Titanium Silver
