Which constellation does the red hat in ancient Egypt represent?

The red hat in ancient Egypt does not actually represent a specific constellation. In ancient Egypt, red headscarves or headdresses usually represented royalty or gods, not specific constellations. In ancient Egyptian religions and myths, different gods or symbols may be associated with different colors, but this is not directly related to constellations. In ancient Egypt, constellations were usually associated with astronomical observation and agricultural activities. Egyptians will observe the stars to decide the best time to plant and harvest, but there is no clear record to link the constellation with the red hat. Therefore, the red hat does not represent a specific constellation.
