How do we see colors?

Answer 1

We see colors by the different wavelength that is not absorbed (or what's being reflected) by the object that we see. These objects do NOT own colors. It's the surfaces of the objects that allows things to reflect or be absorbed. Ex. When I see a red book, the other colors such as orange, yellow, green, blue etc. are being absorbed by that red book from a light source except for the color red. The reflected color(s) (in the example, the color red) is then captured or perceived by our eyes.

Another perspective of "how we see colour?" is that there needs to be some form of light in order for us to see colour and without that light, we wouldn't be able to see colour, let alone see at all. A bonus: If you see white, the object reflects all the wavelength or all the colours. If you see black, the object absorbs all the wavelengths or absorbs all the colours.

Answer 2

We see colour with sensors in retina of the eye called rods and cones. The rods are sensitive to low light and the cones which require a greater intensity of light, are sensitive to colour. Each cone contains one of the 3 pigments sensitive to either RED BLUE or GREEN. The message is passed to the optic nerve and then onto the brain.

Answer 3

We see colors when light enters our eyes and interacts with special cells called cones in the retina. Cones are sensitive to different wavelengths of light, which are perceived by the brain as different colors. The brain processes this information to create the perception of color.
