I agree with Sandee. I'm a ceiling and wall in the same color but not sheen. This is a hotly contested topic which skews to white ceiling, but a few if us hold fast to same color. An even fewer individuals advocate for a completely different color. I'm glad they exist to keep things lively :) There's no hard and fast rule. It does cost a little less to do the same color, labor wise although you'll buy a different sheen. For dark colors go a few/shades lighter for the ceiling.

Your choice of white walI and cabinets is just perfect with your other choices, very clean and fresh. I think the walls and cabinets can be the same color white, but the cabinets should be a different sheen. This is not only for interest's sake, but because cabinets get handled a lot, and in a kitchen with potentially food-covered hands, and a semi-gloss can be easily wiped clean. You can even use high gloss, but the surfaces need to be in perfect condition, or the imperfections will be highlighted. For the walls you can use eggshell or satin (satin has a little more sheen than eggshell) and I would use the semi-gloss on any trim in the room such as window and door casings, moldings, etc. You can use matte on the ceiling, or if you don't want to bother with the third type of paint if you won't be using this color anywhere else, just use the eggshell or satin on the ceiling as well, your kitchen will be nice and bright. If your kitchen doesn't get much natural light or faces north or east I would paint the ceiling the eggshell or satin so that the light in the kitchen bounces around.

I echo the suggestion about sample boards, that is very important! You could pull one of the grays from the stone for your island - I see a dark gray, a medium warm gray, and a blue-ish gray (if my computer is rendering the colors accurately). Again, sample and make sure that the gray tone works with your cabinet choice (that blue might be an alternative to white for the cabinets also). With warm white cabinets, you could find a warm blue or green for your walls, if you want to introduce a touch of color. I like pale tones, to offset the strength of the granite.

I think one of those kinds of colors will look great in your space- and can go with SO many other colors (taupe, beige, white, pink, red, saffron, teal, green, and cobalt)! I have SW Copen Blue in most of the public rooms of my house... It looks pretty much just like this in my house, most of the time. https://www.houzz.com/photos/leland-cottage-craftsman-phvw-vp~14483924 In my family room I have a less saturated but similar color- Valspar's Winter In Paris.
