It is a good choice to mix white and China red, but white should be used in large areas. Red is not suitable for a large area because of its bright color, but it is well decorated.
The background wall of the sofa is white, and several circles of different sizes are made of gypsum board and painted red, which can be painted and pasted with some beautiful plates.
Curtains have a white background and a red curtain head, and red vertical ripples (vertical stripes make the room taller)
Use your favorite red and white sofa. Personally, I think the orange sofa is too dazzling. I suggest not.
When buying furniture in the future, you can go to quanu to see China safflower series, decorated with rattan flowers on a white background. It should suit your room style and be suitable for marriage. In this way, the overall style will be unified, and one or two pots of larger green plants will be fine.
