That's not theory, that really is what happens. Stainless steel 
oxidizes (like rust) when exposed to the atmosphere. However, in a 
nutshell, the Chromium in stainless oxidizes to the surface and 
creates a very thin film. This then seals the steel, and prevents 
further oxidation. In the process, the stainless will become darker. 
I'm not 100% sure if this is because you're now looking at the 
oxidized layer itself, or if it's so thin that it's transparent, and 
filters light. But rest assured, that it will match the rest of the 
car within a week's time.

When performing touch-up work, you MUST resist the urge to make the 
entire car have a universal sheen. Forget handprints, that's the 
hardest part of maintaining the metal finish on your car!
