Your tops look more yellow than the lowers. Wondering if this is more a lighting issue, than a paint issue. What type of lighting do you have in there? A picture of the whole room would be helpful. Try lighting that is cooler white than what you now have and see if it corrects the problem. Do you have under cabinet lighting? The very top of the set of cabinets with the microwave between the top piece and the ceiling, needs to be caulked. I can see a gap there. I do like your backsplash, and think it will look much nicer, if you have proper whiter type light bulbs. The room looks a bit blah though, try to add some color accents somewhere.

IMO blue/ grays are hard to work with if i have a client that has to paint before a house is completed i highly reccomend a pale grayed green it is much more neutral than gray and seems to work with everything. Sea Salt from Sherwin Williams is a good color it is not the same as BM sea salt.

I’m putting in a new kitchen right now too and my cabinets are a light creamy beige color. My island is a cappuccino color. I’m thinking of a medium brown colored antique alloy hardware for the cream cabinets and a brushed nickel for the island. I’m going to bring samples of both home and see what looks best. My pendant lighting is a mix of bronze and silver both antique so thinking I could use the same for the hardware.

The first thing I would do is get a counter depth fridge in that small space and since the space is tiny I think the same as the walls could be a good idea. I certainly would not have done black appliances and with the new cabinet color they will even be more of an issue so think a lot about this change.
