Why Is The Color Red Considered Lucky In Chinese Language and Culture? A constant feature in all things Chinese is the color (colour, for those yank-challanged among y'all) red. 

As common knowledge goes, it is because red is considered to be lucky.

Why?
Here we have an old tale in China, saying that there is a beast called the "Nian" (年獸), and it will only attack people in spring. But it's afraid of all things red.

That's why Chinese people use many red things in the lunar new year (also in spring). It became a common color represent "lucky" in Chinese culture.
