Why do we perceive objects in different colors?

The physical color of an object depends on how it absorbs and scatters light. Most objects scatter light to some degree and do not reflect or transmit light specularly like glasses or mirrors. An opaque object does not allow light to transmit through and instead absorbs or reflects the light it receives. A transparent object allows almost all light to transmit or pass through, thus transparent objects are perceived as colorless. When we view an object of a specific color, some of the light hitting that object is reflected and detected by our photoreceptors in our eye, while other light is absorbed by the object. Black is a color that results from the absence or complete absorption of visible light. We see the ocean as blue because it absorbs the red light and reflects and scatters the blue.
