I had a similar experience with my car, in the sun it looked nice and shiny (you could see the swirl marks etc), but when I put it in my parents garage under the fluoro lights, I could see water marks covering the roof and bonnet, very similar colour temperature between the 2 light sources, but the diffused light from the fluoros hid the swirls, but brought out the watermarks.
You would probably also find that orange light diffuses less (as its closer to the red end of the spectrum) so the scratches would become a bit more obvious, a blue light source on the other hand would diffuse a lot, hiding the imperfections. So just keep parking under those blue light they use to keep the junkies away and you'll be fine.
Nearly all men can stand adversity. But if you want to test a man's character - give him power.
