The object of subtly blending into the surroundings while Overnighting-while-Urban ( or OU) has some other aspects which need some addressing. The reason for the white paint on RV's is it reflects the summer sun keeping the RV cooler inside. This has been proven with autos, but most of do not live in a car down by the river, so it's not a worry. I searched and found a few who experimented with light and dark pigment on their RV's. One researcher found a 15 deg. F hotter interior after 3 hrs. in the sun with a medium brown color compared to a cooler white painted exterior on the very same rig. That is research. It would not apply to Jeanie and I as we do very little summer sunshine camping in the TC.
Another thought is, if you are trying to blend in, in an urban setting the colors are mostly black (road surface, and shadows caused by street lights etc.) and white or off-white buildings AND, the myriad other RV's, pickups, cars, delivery trucks and vans that are omnipresent and in a white appearance. So, if you stay with white everything, you DO blend right in with your surroundings.
The other color in an urban setting is tan or beige with a concrete gray tint i call terra tone. The neutral nature can be used in bricks, rock work, sidewalks, fences, walls, and more. This would indicate sand as a color might work too as it does slowly fade into the night, if non-reflective.
One thread I read mentioned the color of your RV gets darker as you pay more money for it. There is some merit to that argument. Look at how many $500K MoHo's you see that are pure white. Few. Mostly earth tones and a fabulous applique of artwork with wild waves and arching accents: mostly in earth tones.
So it follows that your rig will look more expensive it it is painted other than white.
Many of you have finally comprehended the object of this thread once all the bad connotations of the verbiage I used was deciphered.
I do appreciate all your kind indulgence and wonderful replies. I learn something every time.
I'm not done with this yet.
