Nobody paints like Mother Nature - but how do we see her work?
The answer is that humans perceive different wave lengths of light as different colors. Objects are struck by all the colors. If all the colors are reflected off the object, it is perceived as a white object. If all the light gets absorbed by the object and none is reflected, the object is perceived as black. If the object is blue, only the blue light will be reflected and all other wave lengths will be absorbed by the object. The eye would then perceive the object as blue.
Color is the visual perceptual property corresponding to the categories called red, blue, yellow, green and others each having different wavelengths. The color comes from the spectrum of light (power versus wavelength) interacting with the spectral sensitivities of the eye's light receptors. Mother Nature causes things to appear different, even in different light.
When the light enters our eyes, special cells called photoreceptors tell our brains about the light. Light is made of little bits called photons, and when the sun shines, trillions and trillions of these little bits of light fall on the earth. The photons bounce off of almost everything and some of them enter our eyes - the bits that enter our eyes allow us to see.
Scientists have believed that there are different kinds of photons and the different types give rise to our sense of colors because they are of different wavelengths. The visible wavelength colors from the Sun can be seen when you look at a rainbow when raindrops acting as natural prisms produce the colors.
Our eyes contain two main types of photoreceptors called rods and cones because of their shapes. These cells are located in a layer at the back of the eye called the retina. Rods are used to see in very dim light and only show us the world in black and white.
The other photoreceptors are called cones and allow us to see colors, but are not as sensitive as the rods so they only work in bright light. This is why you see only black and white when you are outside in the evening or in a dimly lit room. There are three types of cones, one for each of the three main colors we see, red, green and blue.
Some people have a genetic defect that makes one or more of the cones fail. This condition is known as color deficiency or color blindness. Color blindness is fairly common, affecting about nine percent of all humans and is much more common in men than in women. - Wikki
