NEITHER! Wood is what they want to be. White will work but colors will be O.U.T faster than you can get sick of it.

Please see note above about not painting. unfortunately that is not an option as the pressed wood is peeling in several spots on the sides (not pictured but it looks terrible).

Tops should be lighter than the bottoms, or the kitchen looks top heavy. As to the fake wood that is peeling, you will need to very carefully clean it well, and sand it well (with out a lot of pressure, very carefully), and then use an oil based sealing bonding primer on it before you do any painting. Some wood cabinets should be painted, and some should not be. Yours need to be painted to protect them, and get more life out of them. Take your time, and use paint that is meant for cabinets, not just regular type paint. Clean them well, and then clean them again. It is probably a very good idea, once you have cleaned well, and sanded well, to use the sealing bonding primer on all the cabinets, so your paint will adhere better.

It would be difficult for me to pick a color while holding up those samples against the existing wall color. For me personally, I would pick the color without the complication of that wall color. Wall color can easily be changed, but the cabinets are the star.

I like the pewter green. Gorgeous!!!

I'm starting another kitchen now, it's going to be Steep Cliff Grey by BM. These only have 1 coat so not great looking yet.

Everyone has their own taste, but I really love color!  I don't tend to love "tuxedo" different colors on upper and lower cabinets.  But at island is nice. Just my opinion, but would hold on wall color decision until you figure out cabinets color

If you must paint, paint white.

Re-read the comment above about colors going out of style quickly.

If color makes you happy, then do it! I personally don't like wood cabinets and wood floor...too much for me as I crave contrast. Since you have a chance to do anything, bring your personality in. The cabinets are older, they will be most likely be replaced if you sell....so make this color choice for you now :)

I would paint but I'd def go a warm shade of white, not colors like you're showing. They're cool toned, dark and will look dark and gloomy vs bright and open like the Gaine's photo. Note all the differences between the kitchens. Her's is huge with TONS of light streaming in from large corner windows, high ceilings. No upper cabs all contribute to very light and very open. Notice there are very few cabs in that room painted the dark tone. I'd definitely paint the window/door trims the same for a brighter look and continuity, maybe the walls too just as you see in her kitchen and most other white kitchens. I wouldn't worry about electrical, you have plenty and it'll be so much brighter after lighter paint.

I painted our dark cabs creamy white to "hold us over" until we could remodel.....6 yrs ago. Now it's likely we'll not remodel. I've painted more cabinets white over the yrs than I can count but this time latex enamel for cabinetry (the best u can buy) didn't hold up at all around the hardware. It wasn't due to any prep issues because I don't take shortcuts; I sand, 2x primer, 2x finish paint but it was peeling around the knobs. I blame my other half to some degree; hardware isn't for using I guess....:)

Anyways, 2 yrs after I painted, I re-sanded, used diff latex paint, same probs. Then I said, OK, enough of this crap, I'm doing OIL based. I painted a few, let them sit for a yr and FINALLY, no problems. It's been 3 yrs now, they're still perfect. You will prob only use 2 quarts, you can do just the doors/drawer fronts. You could use latex elsewhere but for the "finger" areas, oil. Also oil based primer.

Our before kit was dark and depressing; this was the lightest it would ever get during the day. I've since painted the backsplash white, changed a few door fronts out, changed the hood, moved the microwave.

@User posted beautiful Pewter Green pictures and Attitude Gray in the inspiration photo looks great, too. Both have good lighting and ample contrast which are the keys here to a successful refresh as others have already mentioned in the comments. With your existing counters and wood trim and floors I think Attitude Gray is more complimentary. I think your wall color should be the same color in the kitchen and the attached living room and lighter than both the samples you shared more like the bright contrast in the inspiration photo. Good Luck!
