What would the colony need to protect its people from the temperatures on the moon?

To protect its people from the extreme temperatures on the moon, the colony would need robust insulation and temperature regulation systems within habitats. These could include specially designed structures with materials that reflect sunlight and minimize heat loss, as well as advanced heating and cooling systems powered by solar energy. Additionally, protective gear for outdoor activities and the establishment of underground facilities could further enhance safety against the moon's harsh temperature fluctuations.
