fast food restaurants are generally decorated in red and orange. Consumers like red, orange and blue best. Experts said that in the process of designing the space atmosphere of fast-food restaurants, the matching colors of orange, yellow and blue can improve customers' dining mood and turnover rate. People who often eat out may find that the main colors of the fast food restaurants they often patronize are red, orange and blue, and red and orange are the majority. For example, some Chinese fast food restaurants are generally decorated in red and orange, and the plywood can be painted with light gray, such as gray with purple flavor, and then some patterns can be drawn on it for decorative effect, because the bar and wine cabinet in the living room are dark, and the plywood can't be decorated with particularly bright colors, which will make the contrast strong and gray.
