That look is for a powder room, not a kitchen. If you want blue, then paint the whole wall blue -- the copper countertop will set it off nicely.

ETA: You could accent the blue with copper switchplates.

I'd get some posterboard and begin with large samples of the color blue you like and the copper in your space. Lighting will affect the colors. Led comes in different shades of white.

We bought a large amount of this copper metallic paint for a project that was never done. I’ve been looking for a way to use it :-)

when my mind visualizes darker blue and metallic stiped walls I see wider blue stripes with narrow copper. Copper is maybe 25% width of the blue. Would drive you bonkers, but I’d really like would be clusters of 3 copper pinstripes and the wider blue stripes.

As long as it's planned meticulously and the technique is good. It would be easier if it were a symmetrical elevation.

I think your space is starting to look really great. Vertical stripes? Please don’t just do this to use up the paint.

There is too much going on visually to add vertical stripes. But you might be able to incorporate horizontal shapes with custom shelves and decor with copper items. Use copper sparingly.

The floor vent looks like a huge problem because someone will be standing at that sink. Why two small sinks instead of one large sink?

I could more see the copper as a thin stripe on walls the same color as the cabinets.

The sinks are larger than they look, because while narrow they are deep. The left (prep) one is 12” W x 20” D x 12” H, the right (wash) one is 18” W x 20” D x 12” H. I thought of a way to get a few more inches of depth, need to run it by the stainless fabricator. (I wanted to be able to easily soak a stack of half sheet pans or two stock pots, that was my size criteria.)

Why two sinks - the usual reason, I hate trying to prep food using a sink and having someone plop a dirty saucepan or their beverage into that sink. “Oh, excuuuuuse me” they simper while dumping some half-drunk smoothie onto my salad greens in the spinner. My blood is boiling just thinking about it, my fingers clutching an imaginary chefs knife. Breathe.

Oh the blasted floor vent. It’s not a problem that air is coming out - actually it’s rather nice having the AC blowing on you during a hot day - but the vent face is raised above the floor so you are standing on an edge. Worse yet, someone cut the corner off the vent face so it looks bad. No matter, I’m going to find the correct size replacement vent and recess the face to be flush with the wood floor.

Vents in the floor in the kitchen are problematic because of cleaning the floor. A vent in front of the sink is even more problematic because you will be dripping water in it fairly regularly.

And I am assuming you don't go shoeless in the house. We don't wear shoes past the front entry so I could not stand on that.

If your sinks are too deep, your back will hurt.

If you are going to paint that wall with stripes, especially metallic stripes, the finish on that drywall had better be Level 5++.

My daughter thinks blue and copper stripes will give someone a stroke. With the assurance of a young person - who admittedly also has a BFA and knows color and design - she insists on a cream or parchment paint.

It seems to me the medical conditions of my guests are not really my concern, and I’d rather they stay out of the kitchen anyway. But if we do white-ish, I like the idea of thin copper stripes on that, a la palimpset. She says it will look too ”posh”, I think no one will ever use that term for this kitchen.

I agree with your daughter

You could accent with more copper to go with your counters in so many ways in your new kitchen without going stripes on walls. Maybe a beautiful tile with copper colored grout? Or a copper colored schluter?

What about copper hardware? Or great copper pots that are useful AND decorative?

Palimpset, I would like to not have that floor vent, but it is there and moving it would be - well, the ducting is all accessible from the basement, but I’d have to weave in long lengths of tongue & groove floorboard to fill the hole, and it’s not conveniently near one end of the floor. I already have a fair bit of floor restoration to do, and no time to tackle more :-(

So I’ll have to live with it. We usually have mats on the floor at the sink and range, because the former floor was miserably hard stone tile. Maybe we’ll continue doing that, now to reduce splashing on the wood floor, in which case the floor vent will be covered - also a problem, but a different one. Splashes into the vent itself isn’t a problem, the duct has plenty of airflow to dry it out and hasn’t rusted.

I am not sure what the cleaning routine will be for this floor. I’m going to dock a Roomba robot vacuum under one of the cabinets, and have it run automatically at every night.
