2. The color matching recognition of yellow characters on the red background is very low. When people use it as a signboard, whenever they look up, they will find that these words are not easy to distinguish 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, what we are most afraid of is the collocation of red and yellow characters.
3. When we color the signboard, we usually use a warm color with a cool color, which can keep our emotions 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.
