China's trademark office permits for the trademark registration of colors. However, though you can register a China trademark for a color combination, single color trademarks are not allowed. It is also required for China trademark registration that your color combination be distinctive. It is also important that you remember that China is a "fist to file" trademark country so if you want to register your color combination as a China trademark you must be sure to seek that registration first, before anyone else does.

China trademark registration for foreign companies: how to file, own, and enforce your marks, handle squatters, and prepare for the 2027 Trademark Law.

When registering your trademark in China, it is important you choose your China trademark classes wisely and not choose to register in too many or in too few China trademark classes.

China does not require proof of use to register or renew a trademark, but that does not make use irrelevant. Once a registration becomes vulnerable to non-use cancellation—or you need to enforce it—the quality of your evidence can determine whether the trademark is worth much at all.
