Kitchen sofa - which color?

The yellow sofa looks very nice in the picture, but I find the combination of yellow and black hideous. Also, the contrast with the oak wood would be too bland for me: oak table, oak floor, and mustard yellow sofa are so similar in color. If it should be a colored sofa, I think olive is the best of the colors available: olive definitely goes with black. It is a mixture of black and yellow. Also, I would like the gray one; it is harmonious with the black of the kitchen and the white walls and looks elegant with wood. You can bring color in with pillows, towels, wall paint, or pictures, and that can be changed cheaply and easily if you get tired of it. Personally, I would look for a sofa in a warm, dark red or better rust red. Unfortunately, that color is not available for this model. I’m afraid you will hear a lot of different opinions here and end up no wiser than before;)

That's how every Schalke fan feels... We don't have a kitchen sofa, but a bench and chairs upholstered in faux leather. The bench is light gray, the chairs mustard, burgundy, dark green, and dark blue. The table, country house floorboards, and kitchen work surfaces are oak - called wild oak, kitchen fronts matte black. It fits and looks cheerful. So it also works with more than just one color.

That's how it goes for every Schalke fan...

BTW could you please tell me your ceiling height in the kitchen area; that would be helpful. We are currently determining this, and the kitchen area will be kind of "subordinated," the rest of the open-plan space in our home has a gallery. I saw yours once in a photo, but can't find it right now. The goal is to get a still appropriate but not too low room height for it.

:D where Schalke fans are already suffering anyway :(

My kitchen is also a combination of matte black and oak wood, plus a large wooden table, light gray chairs, concrete gray tiles, and a red kitchen wall. With a bowl of fruit, herbs, and flowers, that's colorful enough for me. If we no longer like the red, the wall might become pale green someday...
Everyone's taste is just different, which is why it's so hard to advise. Besides, it very much depends on the room how something appears.

I haven't ordered a sofa yet. I'm waiting until the kitchen is installed (hopefully in two weeks) and the table has been delivered (also hopefully in two weeks).

Then I will post photos here and ask for advice again.
My kitchen sofa actually only needs to meet 2 requirements: armrest the same height as the backrest (it's wonderful for reading. I would never want it any other way) and the length has to fit (the table is 160 cm long). And of course it has to be comfortable and have a nice color. But I assume it will.

Regarding the armrest height question, I came across this sofa and haven't found any other that has it either.

Ceiling height in the kitchen area

224 cm bottom edge of the longitudinal beam (the first one from the gallery area, i.e. passage height into the area under the one gallery part).
236 cm bottom edge of the cross beam
256 cm beam layer (= floor above, 3cm thickness)
