When a color is absorbed, it means that the particular color is not reflected back to our eyes and instead is absorbed into the object. This can happen for a variety of reasons. For example, if an object is a dark color, it is likely that it will absorb more light than it will reflect. This is because dark colors tend to absorb more light than they reflect. Additionally, certain materials can also absorb light. For example, paper is known to absorb blue light more than other colors of light. This is why old newspapers often appear yellowed.
