I don't think you'll notice it in a day or so. No one else will likely notice it either.

Different sheens of the same color can look really different! I think once the backsplash is in, your eyes won't immediately glom onto the crown.

(I had one upper cabinet that came in the absolutely wrong shade of factory-finished white. It sticks out like a sore thumb. That's getting replaced under warranty)

What paint did your painters use for the trim? Was it actually SW Pure White or did they color match to some other brand?

My color matched BM Chantilly Lace cabinets and my BM Chantilly Lace trim match perfectly.

It was sherwin williams. funny thing is that it matches the extra white paint chip pretty well. and when i went into my neighbors house that has extra white trim the chips look the same as in my house…

You think the trim is extra white?

no empty cans to make sure.

Why are there no empty cans?? Usually there is touch up paint left over. I dont think it clashes, and I do think you will get used to it over time, but, for peace of mind, I would want to know. I would go buy a quart of the sherwin williams paint myself, and prime and paint an extra piece of the trim, and hold it up by it. Make sure you get the exact same sheen as what is already painted on the trim. If what you get, matches your cabinets, then they have put a different color on the trim, and need to redo it.

what colour is the wall? It seems to match your cabinets perfectly.

@w0lley32 my walls are sw heron plume.

Paint colors are notoriously variable, even when you hold things like brand and product constant. I have three cans of BM paint right now that are all ostensibly the same color but were mixed by two different shops and they are all a bit different, even though that's a machine with a formula doing the mixing. It is also possible that they got the color wrong for yours--the color names are quite similar if it is in fact the Extra White, and I've found at our local paint shops that many of the staff have the codes in their head for the many whites and will key them in when you tell them the name, so there's room for human error too even if your painter said "Pure White."

I'd take a cabinet door to the paint shop and have them match the color, and then repaint the trim in that shade. Without the cans of paint in hand, it's hard to know if the current color is the wrong one or, if it is, whose fault that is. (If it's a large painting company they may have an account at the paint store with a record of the color they purchased, but that's a bit of a long shot, and you'd still somehow need to get a sample of the color on the trim in for them to check.) Good luck!

You think the trim is extra white?

Yes.

When I went to the paint store they knew the painter and looked it up and said pure white was bought. So i guess its just off that much. They cant scan the trim and tell me what color it is but just get formula if i need a match. The lady dabbed their extra white base on the extra white paint card and it didnt match up either. She said their really isnt much difference between extra white and pure white just a drop of gold. 🤷‍♀️ So will just have to live with it.

Hopefully tiling around window to the ceiling will make it blend in more in that one spot.

If it helps, many people intentionally choose different trim and cabinetry colors, so it is likely the kind of thing that will bug you because you know they were supposed to match, but that others won't notice because they won't realize they were ever intended to be the same. I'd finish up the rest and see how it comes together--if it still really bothers you, you can always repaint then.
