The walls are blue, so what color sofa should I choose?

I don't know if the blue you are talking about is a more bright blue or a light blue with a relatively low purity, the general brush wall is mainly light color, not depressing, if it is light blue, then I think the pure white sofa (a bit of Mediterranean style feeling), a little stronger yellow (blue and yellow are more complementary, more romantic and warm feeling), if it is a bright green (it will be more interesting and energetic) is also good. The above colors are all of a bit purer, so I think they contrast with the pale walls. Otherwise, it is all light blue and light yellow, and the feeling is not opened.

Imagine it for yourself.

If it's a vivid blue or a deep blue, it's probably just one wall. It is recommended that beige and beige are fine. That is to say, this line is light. Oh personal opinion, for your reference!

If you use blue as the main color, then you are using cool colors as the main color. Once this theme is decided, the other colors and accessories of the room are in harmony with it. It is recommended to use white and light green for other accessories in the room, which is suitable for blue.

However, due to too much cold color, the room will be deserted, which is very unpleasant in winter. Therefore, it is necessary to increase the composition of warm colors appropriately, but the red series in the warm color is too abrupt, and you can use bright yellow, which is a light warm color series. I hope I can help you.

White or off-white is fine, I personally think.

I suggest you choose fruit green, it's beautiful!

The red one is also dirt-resistant, and the color contrast effect is good.

White or milky, that is, unstained.
