Do what makes you happy! But I would comment that your space doesn't get a lot of light so if you are going to commit to dark, you might need to upgrade some of the lighting if you like to cook. I think a lighter color would actually offset your cabinets better but if your aesthetic is dark and sexy, go for it. I would definitely do a more streamlined valance or maybe nothing at all-- a bright white trim could offset any dark paint color and give the room some extra visual interest. Leaving the windows bare would also allow the maximum amount of light to come in.

I am not a fan of the accent wall idea in a space with cabinets. Unless its a big bare wall in a big minimalist space. I think in this space it might be too much going on.

Your house, so if you want dark walls in the kitchen….

I would advise against Kendall Charcoal as it has a distinct muddy green undertone in the wrong light.

Keeping the stain of your cabinets in mind, try a dark paint in blues instead. (B.M. color strip in the 1640”s)

You can go for a darker color BUT please make sure you have adequate lighting. It looks pretty dark as is so IMO you probably shouldn't but it could look nice if you invest in more lighting.

You have dark cabinets and not a lot of natural light -- it'll be like a cave in there if you go dark. You mentioned wanting dramatic --> try a bright color instead of a dark color.

Remove the window covering and leave it bare. It will look good and give you more light.

I think continuing Pewter Revere into the kitchen would look nice.

First things first. Your kitchen already needs lots of supplemental lighting. Start there. Bright under cabinet lights, over cabinet lights, lots of recessed lights, and reassess those pendants that aren't really giving you any light. Do that before you do anything else.

I don't have a big kitchen AT ALL and only only one small window, so was worried about it looking really dark. However, my cabinets and counter are white-ish. I took a leap of faith and used BM Hale Navy and LOVE it. I also have undercabinet lighting and recessed in ceiling which helps

You have a cave already. If you want to make that read cozy and warm, that involves about 3K worth of electrical work and lighting. Then you can use dark and dark together. But it requires a skilled layered approach to get right. And those layers start with lighting. Wall washers especially.

Decor on top of cabinets really isn't a good look because that's not where you want the eye to be drawn, in a room. Use the lighting you have.
