Not really. It's hard enough touching up washable paint after more than a year if you have the exact paint that was used much less trying to match it. The sheen dulls over time and the color fades over time which is why touching up is so hard.

If there is a ridge, then you can sand it and if that doesn't work then it needs to be patched.

I have the Ivoire formula for Emerald matte on the can and it is correct according to the official recipe for Ivoire paint in a gallon (double checked). The base paint is correct too. But the gallon colour does not even resemble the paint chip or the Color-to-Go. When I discuss the mismatch gallon, I'm directly comparing the paint they gave me spread on the paint chip - and the gallon Ivore was not even close to the same colour as the paint chip. Quite truthfully, it is like a lighter version of Believable Buff - I'd accept it as a match for Believable Buff before I'd accept it as a match for Ivoire!! In terms of how the real Ivoire looks on my walls (the paint chip/Colour-To-Go version, not the mismatched gallon paint), I have painted Ivoire on a lot of test walls, so I have a good feel for how it appears in my house - yellow with apricot undertones and I absolutely love it. This faulty Ivoire looks like a kind of muddy/murky beige-yellow - not the same colour at all. I was flabbergasted when the gallon of Ivoire looked like an entirely different dingy beige colour - even the guy who mixed it thought it did not seem correct but he wanted me to take it home and see how it looked at home in the lighting it would be in.

Having to look at that every day would drive me nuts. You could call the company that manages the building and ask the name of the painting company and find out from them where they get their paint - Ben Moore or otherwise. In some towns, there is one paint company that many of the contract painters use. What's the closest paint store to the building? The ceiling is probably the Ceiling White paint of the company where the paint was purchased. You might be able to remove the darker gray from the trim with some sort of paint remover like Goof Off. Failing the above, I would try to figure out what sheen of Gray Owl was used, then buy a quart and some masking tape and go to work on it. Whatever you do can't be much worse than what's there.
