5. The lighting system of claim 1 , further comprising a monitor wherein a portion of the image displayed on the monitor is greater than the examined region.

6. The lighting system of claim 1 , wherein the remote image sensor utilizes a frame grabber to provide the examined image to detect at least one color and intensity characteristic by the image remote sensor.

7. The lighting system of claim 1 , wherein the remote image sensor converts the color and intensity characteristic into the output signal with an R-G-B bitmap format.

8. The lighting system of claim 1 , further comprises an additional sensor coupled to said at least one control unit, wherein the additional sensor is configured to detect at least one color and intensity characteristic of current lighting conditions and wherein the control unit compensates the control signal for current lighting conditions.

9. The lighting system of claim 8 , further comprising a mixing chamber configured to receive light from said natural light source and light from said at least one multimode artificial ambient light source.

10. The lighting system of claim 1 , wherein said at least one multimode artificial ambient light source comprises a plurality of light emitting diodes (LEDS), wherein each of said plurality of LEDS is individually addressable and controllable by said at least one control unit.

11. The lighting system of claim 1 , wherein said at least one multimode artificial ambient light source is disposed within at least one solar tube.

12. A lighting method, comprising:

detecting at least one color and intensity characteristic and producing an output signal to at least one control unit based on said color and intensity characteristic with a remote image sensor wherein the remote image sensor utilizes a frame grabber to provide an image of a video to detect at least one color and intensity characteristic by the image remote sensor;

outputting at least one control signal to at least one artificial ambient light source by said at least one control unit; and

outputting light of varying color and color temperature by at least one multimode artificial ambient light source in response to said at least one control signal and wherein the remote image sensor utilizes only one pixel for said color and intensity characteristic.

13. The lighting method of claim 12 , wherein the remote image sensor utilizes a region of an image detected smaller than the area of the image detected.

14. The lighting method of claim 12 , further comprising:

displaying the video on a display.

15. The lighting method of claim 12 , wherein the remote image sensor converts the color and intensity characteristic into the output signal with an R-G-B bitmap format.

16. The lighting method of claim 12 , further comprises an additional sensor coupled to said at least one control unit, wherein the additional sensor is configured to detect at least one color and intensity characteristic of current lighting conditions and wherein the control unit compensates the control signal for current lighting conditions.

17. The lighting method of claim 12 , further comprising a mixing chamber configured to receive light from said natural light source and light from said at least one multimode artificial ambient light source.

18. The lighting method of claim 12 , wherein said at least one multimode ambient artificial light source comprises a plurality of light emitting diodes (LEDS), wherein each of said plurality of LEDS is individually addressable and controllable by said at least one control unit.

19. A lighting system, comprising:

at least one multimode artificial ambient light source;

at least one control unit coupled to said at least one artificial ambient light source and configured to output at least one control signal to said at least one artificial ambient light source wherein said at least one multimode artificial ambient light source is configured to output light of varying color and color temperature in response to said at least one control signal;

one remote image sensor coupled to said at least one control unit, wherein the remote sensor is configured to detect at least one color and intensity characteristic of an image in a video and output an output signal to said at least one control unit, based on said color and intensity characteristic detected by the remote image sensor utilizing a frame grabber to provide the image to detect at least one color and intensity characteristic; and
