The color red has symbolic significance of good fortune in China. Incidentally, it is also a symbol of communism.

But have you ever heard the term "red scare"? Many people from the US almost seem like bulls with the way they freak out at anything remotely resembling communism (read: any progressive policies in general), like UBI, raising the minimum wage, improving the healthcare system, especially anti-hate speech regulations (I wonder why!), high-speed rail, protection against infectious diseases, and so on.

Red is one of my favorite colors too! And it's very harrowing to observe how the conservative racists in the US have appropriated and completely shitted on it.
