It is not illegal. According to regulations, modifying the vehicle's color within 30% of the body is allowed. Both decals and paint are permissible, as long as they do not exceed 30% of the vehicle's surface and avoid colors used by police, hospital, military, or engineering vehicles. Additional information: 1. Introduction to rearview mirrors: Rearview mirrors are tools that allow drivers to directly obtain information about the rear, sides, and lower parts of the vehicle while seated in the driver's seat. For the convenience of drivers and to prevent traffic accidents and ensure personal safety, all countries mandate the installation of rearview mirrors on vehicles, and all mirrors must be adjustable. 2. Interior rearview mirror: The interior rearview mirror allows drivers to check the rear situation without significantly changing their forward view while driving. 3. Exterior rearview mirrors: Passenger vehicles typically mount exterior rearview mirrors on the doors. In Japan, some passenger vehicles also mount them on the fenders. 4. Undercarriage mirrors: Undercarriage mirrors enable drivers to see areas beyond the front and rear wheels beneath the vehicle body through the mirror directly in front of the driver's seat. This helps drivers spot people or obstacles near the wheels or the vehicle's sides when reversing or starting forward, preventing injuries, damage to objects, or vehicle harm, thus providing convenience and safety to the driver.

Regarding changing the color of rearview mirrors, I have to say, based on my years of driving experience, it might actually be illegal. A buddy of mine last year put a dark film on his car's rearview mirrors—it looked super cool—but he got pulled over and fined during an inspection. The reason is simple: rearview mirrors are critical safety components and must maintain clear reflectivity. Once their color changes, such as becoming darker or non-reflective, it affects your ability to see vehicles behind you. This is no small matter—many places, like China's traffic laws, have strict regulations. Modifications that impair functionality are considered illegal. Safety first! I suggest checking local regulations or consulting a professional repair shop before making any changes, to avoid trouble and danger. If you're after personalization, consider modifying the interior or non-safety components instead—don’t gamble with your safety.

As a seasoned driver with decades of experience, I must warn you that changing the color of your rearview mirrors could indeed be illegal. Regulations require that rearview mirrors maintain proper reflectivity to ensure clear visibility while driving. Altering their color in a way that compromises this function violates safety standards. I once witnessed a neighbor who sprayed colored paint on his mirrors, nearly causing an accident at night due to poor visibility of approaching vehicles, and was later fined by traffic police. While local regulations vary, modifying safety devices is generally prohibited. Consider this: not only could you face fines for violations, but your insurance might also refuse to cover accidents caused by such modifications. My advice? Stick to factory settings or use compliant products—don't risk safety for aesthetics. A quick check on the DMV website or consultation with professionals can save you trouble. After all, as the old saying goes, safety is the greatest blessing.

From a car modification enthusiast's perspective, I advise caution when changing rearview mirror colors. I personally tried spray painting but removed it after noticing reduced reflectivity, which may violate regulations as laws emphasize clear mirror reflection. Some kits are designed to avoid this issue - prioritize certified products. While modifications are fun, never gamble with safety. Check local regulations or test reflectivity before proceeding to avoid fines. True enjoyment lies in exploring within the rules for lasting satisfaction.
