colors
Optical light refers to light that is visible to the human eye. It consists of a range of wavelengths within the electromagnetic spectrum that enable us to see objects and colors. Optical light is often used in imaging and communication technologies.
reflect
cones provide sharp images in bright light and enable us to see in color (color cones only detect red, blue and green, all other colors are made of these 3 colors)
no because you need light to see
You see the colors of light that are reflected off the object. The colors you see depend on the wavelengths of light that the object reflects. For example, if an object reflects green light and absorbs all other colors, you will perceive the object as green.
You can use a prism to see all the different colors in white light.
White light contains the many colors you see. The illuminated object will absorb and reflect the light as its' materials see fit. A black object will absorb all colors. A white object reflects all colors. Everything else lies in between there somewhere.
