What does a red hat mean in Tibet?

In Tibet, a red hat typically signifies the Gelug school of Tibetan Buddhism, also known as the Yellow Hat sect. The red hat is worn by certain monks and lamas, particularly those in higher positions, and symbolizes their commitment to the teachings and practices of this tradition. The color distinction helps differentiate between the various Buddhist sects in Tibet, with the Gelug school being founded by Tsongkhapa in the 14th century.
