Rural gate tiles are not suitable for couplets with yellow characters on a black background. According to the problem network, it can be seen that the ceramic tiles of rural gatehouses are not suitable for couplets with yellow characters on a black background, and temples generally use yellow characters. It is best to write in black, which can better reflect the festive atmosphere and is not grandiose. Traditional culture, such as marriage, is written in red paper and black characters, and few families use yellow characters. Generally, our traditional Chinese characters are all black, and gold is recently printed, so most of them prefer traditional Chinese characters. Gold fonts with red paper are more pleasing to the eye in perception, with bright gold and festive red. New Year's couplets are a celebration.
