1. A system for correcting a vehicle light comprising a light lens including a base panel made of a transparent plastic material, the base panel having an outer surface and an inner surface on opposite side to the outer surface, an outer paint layer disposed on the outer surface of the base panel, and an inner paint layer disposed on the inner surface of the base panel and having a light-transmitting hole formed therein; and a light source installed to be spaced apart from the light lens, the system comprising:
a light source controller configured to control the light source of the vehicle light;
a memory configured to store target color coordinates which are color coordinates of light to be implemented through the vehicle light;
a measurement unit disposed outside the vehicle light and configured to measure color coordinates of light emitted through the vehicle light; and
a correction controller configured to control the vehicle light to generate light having the target color coordinates through the light source controller, to measure color coordinates of the vehicle light through the measurement unit, and to cause the light source controller to perform color coordinate correction control of the light source as much as a difference value between the target color coordinates and the measured color coordinates of the vehicle light,
wherein the inner surface of the base panel is positioned to face the light source,
the correction controller derives the difference value between the target color coordinates and the measured color coordinates, and
the light source controller causes the light source to emit light after changing color coordinates as much as the difference value such that color coordinates of light measured by the measurement unit reach the target color coordinates.
