What Causes Gold To Be Yellow?
Gold looks yellow because it absorb blue light more than other visual wavelengths of light; as a result, the reflected light entering the eye is deficient in blue as relative to the incident light. Because yellow is a complimentary color to blue, a piece of gold that is exposed to white light appears yellow to human eyes.
