Make the restaurant look more energetic. Many restaurants will use black as the main color, and then use other colors to make the restaurant look more dynamic. In the current restaurant design, dark tones are used as a strategic color. I read an interview with a restaurant designer in an article in the spoon class. The designer said: Most restaurants with black as the main color, and most seats are for friends with less than 4 people to get together. The extensive use of black will create a more intimate and romantic environment.
