Some people think that black characters are better, because the biggest difference between China's architectural color and western architectural culture is that China's architectural color is bright and active, even changeable, and bright colors on white background are forbidden, so it is generally best not to use gold.
Others hold different views. They think gold is better, because Spring Festival couplets and blessings have auspicious meanings in traditional festivals in China. Gold is the color of noble atmosphere, which can attract people's attention and represent fortune and good luck.
Generally speaking, choosing black or gold depends on personal preference and cultural background. No matter which color, you can create a unique atmosphere and style at the entrance.
