16. The food display system of claim 13 , wherein the light source is configured to emit a red light and a blue light.

17. The food display system of claim, 16 wherein the blue light has a wavelength of about 430 nm to about 525 nm and the red light has a wavelength of about 600 nm to about 665 nm.

18. The food display system of claim 13 , wherein the at least one cooling Peltier device is configured to cool the food surface below an ambient temperature or heat the food surface above the ambient temperature.

19. The food display system of claim 18 , wherein the light source is configured to emit a red light when the Peltier device is heating the food surface above the ambient temperature, and wherein the light source is configured to emit a blue light when the Peltier device is cooling the food surface below the ambient temperature.

20. A food display system, the display system comprising:

a base, the base comprising:

a top surface, the top surface comprising one or more serving surfaces supported by the base; and

at least one Peltier device contained within the base and configured to change a temperature of at least one of the one or more serving surfaces; and

a support engaged with the base;

a canopy supported by the support, the canopy having a top surface, a bottom surface, and an edge surface between the top and bottom surfaces, the edge surface having at least a first portion and a second portion; and

a light source configured to provide light to the first portion of the edge surface of the canopy and illuminate the second portion of the edge surface of the canopy.

21. A food display system, the display system comprising:

a base;

a support engaged with the base;

a canopy supported by the support, the canopy having a top surface, a bottom surface, and an edge surface between the top and bottom surfaces, the edge surface having at least a first portion and a second portion; and

a light source configured to provide light to the first portion of the edge surface of the canopy and illuminate the second portion of the edge surface of the canopy;

a temperature change source configured to raise the temperature of the food item above an ambient temperature;

wherein the light source is configured to emit a red light having a wavelength of about 600 nm to about 665 nm; and

wherein the canopy is configured to be located above a food item.
