SUMMARY
The optimal color for a collector to achieve the best cooling effect in night clear sky radiative cooling is black, particularly in the infrared spectrum. This conclusion is based on the discussion among participants who emphasized the importance of color in maximizing radiative heat loss. Black surfaces effectively absorb and emit thermal radiation, enhancing cooling efficiency during clear nights.
