1. A refrigerator comprising: a cabinet having a storage chamber;a first door that is configured to open and close the storage chamber, the first door comprising: a frame through which a first hole is defined;a door storage part disposed on the frame; anda lighting device extends along a vertical direction on the frame and that is configured to illuminate the door storage part, the lighting device comprising: LEDs that are accommodated in a groove formed on an inner surface of the frame that defines the first hole and that are arranged in a longitudinal direction along the inner surface of the frame; anda cover member mounted on the groove and configured to cover the LEDs to transmit light that is emitted by the LEDs;a second door through which a second hole is defined, the second hole facing the first hole, the second door configured open and close the first hole of the first door, the second door comprising: a front panel that is formed of a transparent material and that is configured to cover the second hole of the second door and to form a front appearance of the second door; andan insulation panel formed of a transparent material and provided behind the front panel; anda colored layer disposed on a rear surface of the front panel and configured to partially transmit therethrough light that is emitted from the lighting device to an outside of the refrigerator; andat least one processor configured to control the lighting device to enable a user to see stored food in the door storage part through the second hole of the second door due to transmission of light inside the storage chamber through the insulation panel and the front panel,wherein in a state in which the lighting device is activated, the light emitted from the light device is sequentially transmitted through the cover member of the lighting device, insulation panel of the second door, and the front panel of the second door, andwherein a part of the light emitted from the lighting device is transmitted to an outside of the second door. 2. The refrigerator of claim 1, further comprising a sensor configured to detect whether a user is within a predetermined distance from the refrigerator, wherein the at least one processor is configured to activate the lighting device based on the sensor detecting a user within the predetermined distance from the refrigerator. 3. The refrigerator of claim 1, wherein the insulation panel of the second door is configured to seal the second hole of the second door. 4. The refrigerator of claim 1, wherein the insulation panel of the second door comprises: a first glass panel;a second glass panel that defines an insulation space with the first glass panel; anda sealing member that is coupled to edges of the first glass panel and the second glass panel and that forms an airtight seal of the insulation space. 5. The refrigerator of claim 1, wherein a thickness of the second door increases from right to left. 6. The refrigerator of claim 1, wherein the frame comprises: an outer case that defines a front frame of the second door;an inner liner that defines a back surface of the second door; andan insulation material that is located in a space that is defined between the outer case and the inner liner and that is located outside of the second hole. 7. The refrigerator of claim 1, wherein the insulation panel of the second door is located behind the front panel of the second door, and defines an insulation space with the front panel. 8. The refrigerator of claim 1, wherein the front panel of the second door is larger than the insulation panel of the second door and is configured to cover a front surface of the second door. 9. The refrigerator of claim 1, further comprising an additional lighting device configured to illuminate an inner space of the storage chamber, wherein the inner space of the storage chamber and the door storage part are viewable through the first hole of the first door and the second hole of the second door from outside the refrigerator based on the activation state of the lighting device and the additional lighting device.
