A soft, warm grey shade would look lovely, and can be as dark or light as you want. A warmer shade will work with the brown stained wood floor, and the grey will complement the black granite. You could have an undertone of green, blue or tan if you didn't want a pure grey. And it would look nice with any silver metal hardware, either polished or satin/brushed, so you could choose pewter, chrome or nickel. It would still work with white trim too.

@Studio Chippan, Thank you, for your response and the reference pictures. It offered me helpful insights. I agree with you regarding the 3rd-photo. This illustrates that 3 paint colours in my living-room will not work (even if 2 of them are white!). This also means that I can no longer go with 8300/Confetti as my choice of white for walls (as much as I like it, it will dull/dim my rooms if I paint that on my ceilings as well, especially my north-facing rooms). So now, I need to find 1 single-white that can go/complement with my 2 adjacent accent walls in 8307/Quicksilver, and that can be used on my ceilings as well (and the walls and ceilings of all the other rooms). Any suggestions? So far I have sampled the following Asian/royal white(ish) shades (I’ve added my take on them beside it, but it is only my own perception of these shades): 1) Base White (the one without any tint): boring, clinical, too bright a white for walls 2) 8300 /Confetti: not too cold, not too warm, my favorite white among the ones sampled, but too dull for the ceiling 3) L104/Cotton Wool: seems to have a slight-pink-undertone(?) on my walls, too bright a white for walls 4) L109/Icy Peak: boring, slight-green-undertone(?), but might work for my walls+ceilings requirement 5) 8332/Snowflake: this is a very nice grey, but I am looking for a white (for walls+ceilings) 6) 8308/Whispering Smoke: this is a very nice grey, but I am looking for a white (for walls+ceilings) 7) 9483/Clear Sky Night: this is a nice grey, but I am looking for a white (for walls+ceilings) 8) 8299/Ice Age: this is a nice grey, but I am looking for a white (for walls+ceilings) 9) 8292/White Gold: this is too warm a white (strong pink/peach undertones!), ruled-out. Why 8307/Quicksilver, and why 2 accent walls (if I may call it that) instead of 1? This particular vertical-line of the fan-colour-deck is the best match with a wallpaper that will be applied on an exposed beam (~L:15’+15’*H:1.5’*D:4”) running along the ceiling on 2 of my living room walls. Shades along this deck-line are: 8308/Whispering-Smoke (one of the whites you suggested above, but too light a grey for accent), 8307/Quicksilver (seems like the right density for me), 0615/Silver Grey (gets too dark for me from here), 0643/Steel Grey, etc… *Disclaimer: I do not claim to be a minimalist; I am merely trying to be one. However, I did not succeed with my living room design; and now I only hope it doesn’t get out of hand and OTT.

Teal is a very trendy colour, but having it on all four walls may be an overkill in the kitchen, especially with that dramatic chevron dado tile. I hope at least the 4th wall is white! The cabinets have to be white too

Hi Stones provide a better finish than tiles.
