Yellow is the color of learning.
It represents spring, as well as mental development, peace, and meditation. Participants at spring festivals wear yellow, and it’s the traditional color worn by single girls in search of a partner. Vishnu, the God of Protection and Preservation of Good is often depicted wearing yellow garments, along with Krishna, the God of Tenderness and Love, and Ganesha, the God of New Beginnings.
