Rho Galaxy paints its units a combination of a light sand color on the front, fading to black on the sides and legs of the ‘Mech. Battle armor  units follow a similar pattern. Aerospace units are painted with the lighter color on top and black on bottom surfaces. Tanks and other armored vehicles paint the front of their units tan and black toward the rear and sides.
