The best color of a signboard is white characters on a red background or yellow characters on a white background. The reason why yellow characters on red background can't be used is that the recognition is inappropriate: the recognition degree of color matching of yellow characters on red background is very low. When people use it as a signboard, whenever they look up, they will find it difficult to distinguish these characters immediately. If they can't attract customers at first sight, the customer turnover rate will be high in the future, which is not conducive to future business.
Therefore, when we choose the color of the signboard, we are most afraid of the collocation of yellow characters on the red background; Inappropriate color mood: When we color a signboard, we usually use a warm color with a cold color, which can keep our mood calm and make people feel happy. Yellow and red are warm colors, and they are very hot warm colors. If the two colors are matched, it will definitely lead to people's anxiety, and even conflict with people because of impatience, which is not conducive to business.
