PURPOSE: A color control device of a vehicle light for changing the color of the light according to humidity variations is provided to automatically transform the vehicle light to an optimized color and brightness by detecting the situation outside through a humidity sensor, thereby maximally securing the view of a driver. CONSTITUTION: A humidity sensor(100) senses external humidity. A variable resistor is connected to a plurality of LEDs(400). A control unit(200) receives a detection signal of the humidity sensor and compares a humidity value of the detection signal and predetermined humidity information and a resistance value according to the humidity value. The control unit controls the lighting and brightness of each LED by adjusting the resistance value of the variable resistor to a resistance value corresponding to the humidity value of the detection signal.
