Do these sound like a good combination for a kitchen?

I'm not in favor of it. Light oak has a yellow cast to it. and a very heavy grain. It's considered warm in tone.

Putting a brushed nickel on it brings a cool tone to it as do the stainless (grey) appliances. Dark brown in countertops and floors? Those will soak up light and make it very dark. Every time you use flour you're going to hate it. They might also have a red undertone if they're in that espresso color so common now. And rough tile backsplash is hell to clean. I don't know what shade of blue you're interested in if its the Tiffany blue and brown combo you like, then use a whitewashed wood cabinet instead of the oak, then your kitchen won't suffocate in the dark you'll have your cools working with each other and the darks being a counterpoint.

Use a smooth tile, in a color you take from the countertop. You do have to consider ease of cleaning in a kitchen. If you like things your way when it comes to resale time its going to be a problem, but if you like it, it is your house. Do consider the balance between light and dark no matter what shades you choose.

our kitchen was recently re-modeled. we now have an open concept into our family room.

we have a cream white cabinets and wall cabinets, quartz countertops - it's a mix color of black, grey, white, and some brown. with quartz countertops you get more uneven pattern of colors then you would with granite.

our floor is a medium dark wood floor. we originally wanted really dark stained wood, but when our guys did it, there was an issue with random blotness of dark black spots that didn't look natural, so we had to re-stain it a lighter dark brown color.

we have a backsplash that's silver and grey, even tile square pieces with a design "window" over our stove.

Sounds fine but a little boring.
