How are we able to perceive an object as being the color yellow?

• All colors of visible light are absorbed by an object and then yellow light is reflected into our eye.

• All colors of visible light are transmitted to an object, but only yellow light is absorbed by the object.

• All colors of visible light are transmitted to an object, but only yellow light is reflected to our eye by the object.
