I completely get your point. One of the reasons I hate my black Mercedes. I think you can objectively trade it in for more than you paid and get your white RHO. Trust me when I say the stress level drops dramatically.
After 2 years I finally replaced the factory brake pads that left my wheels black after two days. My car looks a bazillion times better even after a week compared to one day with the old pads but it’s still a black car.
All that being said, the stress level dropped but would be even better with a lighter color.
Trade it. You’ll be happy you did.
