Yellow is the color of daylight, but may also represent corruption or humility.
Yellow in Christianity
As the color of light, yellow may be used to represent divinity in Christian art. However, because yellow light is not pure white, it may also be used to symbolize corruption and degradation.
Yellow in Buddhism
Yellow has the highest symbolic value in Buddhism through its link with the saffron robes of monks. This color, previously worn by criminals, was chosen by Gautama Buddha as a symbol of his humility and separation from materialist society. Saffron yellow thus signifies renunciation, desirelessness, and humility. It is the color of earth, thus a symbol of rootedness and the equanimity of the earth.
