You take a piece of trim or a door to your local SW and get their best color matcher to work with the spectroscope to match it. Even then, the gloss levels will be different, which makes the shades appear different. "Matching" 100% is a futile endeavor, unless you buy all of your crown from the cabinet company. Which I have had obsessed customers do. And then insist it was a different color, when it was the lighting. Because lighting on different planes will impact the appearance of even the same exact color, cut from the same exact material.

I took a drawer front to my local paint store (Sherwin-Williams in my case), and their color-matching tech got super close using their scanner. It wasn’t 100% perfect in every light, but honestly, it’s close enough that no one notices unless I point it out. Spraying the catalyzed paint from the cabinet supplier was a hassle I wanted to avoid, so I went with a high-quality acrylic enamel for the trim instead. Worked like a charm

^^^^, all you can get in the two completely different paint types is close. The sheen will never match, which will make the color look different.

Are you painting the trim in all the house or just the kitchen? I would not want that darker off-white as the trim throughout my house. One of the many things that need to be considered when starting/planning a project and not at the end!

The crown of the cabinets look much darker in the picture than they actually are.. They are a warm off white. I took this picture when the difference is starkest. The non-cabinet crown is getting the most light relative to the crown on the cabinets at this time of day.

I have seen some anecdotal accounts that SW stores are better at this sort of thing than BM. Is that the consensus opinion? I am not expecting to get 100% given that I'll be using brushable paint vs catalyzed lacquer on the cabinet but I am hoping I can get pretty close where it wont be as glaringly obvious as it is now.

Our painter is a SW guy, and when we installed all new windows 2 years ago (unfinished pine casings), he took a piece of our current baseboard (oak stain on pine) to SW and I have to tell you, you absolutely cannot tell the difference to all the old baseboards and door casings. They matched it perfectly. It's worth a shot to try SW.

I had it matched at Sherwin Williams and it is close but I think it can maybe get closer? Idk. Should I put a drop of paint on the back of the cabinet door? Do we think that have it on different surfaces make it look more contrasting than it is?

Look at all the shadows. This "changes" the paint color even if you nail it. I wouldn't be too fussy.

I spoke too soon. It actually is perfect. I painted some Painters tape and when sitting flat the color and sheen are almost a perfect match.
