What makes the ocean blue? Why does sand look tan? To understand color, we need to know a little bit about light. Light is a kind of wave, just like radio waves. The only difference between radio waves and visible light is the wavelength. X-rays, radio waves, and light waves are all part of the same electromagnetic spectrum. But only certain wavelengths can be detected by the human eye. Each of these wavelengths is a different color.
Light from the sun may not seem to have any color. But in fact, every color of the rainbow is already in sunlight. Together they make white light. Sunlight is a mixture of different colors or wavelengths. This mix of colors and white light is what lets us see colored objects. When sunlight hits a beach ball, we see only the light that bounces off of it. Different parts of the ball reflect different colors. The yellow side reflects yellow light. The blue side reflects blue light. The wavelengths that don't bounce off get absorbed as heat. Only the colors that bounce off reach your eyes.
The color of light coming from an object is what gives it color. Light travels into the eye to the retina located on the back of the eye. The retina is covered with millions of light sensitive cells called rods and cones. When these cells detect light, they send signals to the brain. Cone cells help detect colors. Most people have three kinds of cone cells. People without all three see fewer colors, sometimes called color blindness.
Some cones respond more strongly to blue light. Others pulse faster in response to green. Every color stimulates more than one cone. Their combined response produces a unique signal for each color. Millions of different colors can be distinguished this way. Each cell detects a different part of the picture. Nerve signals from the eye are sent to the brain along the optic nerve.
The brain will decode these nerve signals to create a mental image. The optic nerve carries these nerve signals to the visual cortex on the back of the head. The nerve signals arrive in the visual cortex, where an image begins to form. Various parts of the brain analyze color and shape, movement and location, and a conscious perception is created.

A photoreceptor cell is a specialized type of neuroepithelial cell found in the retina that is capable of visual phototransduction. The great biological importance of photoreceptors is that they convert light (visible electromagnetic radiation) into signals that can stimulate biological processes.

The human eye and brain together translate light into color. Light receptors within the eye transmit messages to the brain, which produces the familiar sensations of color. Newton observed that color is not inherent in objects. Rather, the surface of an object reflects some colors and absorbs all the others.
When light hits an object, the object reflects some of that light and absorbs the rest of it. Some objects reflect more of a certain wavelength of light than others. That's why you see a certain colour. For example, a lemon reflects mainly yellow light.
When light hits an object, some of the spectrum is absorbed and some is reflected. Our eyes perceive colors according to the wavelengths of the reflected light. We also know that how we see color will be different depending on the time of day, lighting in the room, and many other factors.
Rods don't help with color vision, which is why at night, we see everything in a gray scale. The human eye has over 100 million rod cells. Cones require a lot more light and they are used to see color. We have three types of cones: blue, green, and red.
Light travels into the eye to the retina located on the back of the eye. The retina is covered with millions of light sensitive cells called rods and cones. When these cells detect light, they send signals to the brain. Cone cells help detect colors.
When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photoreceptors turn the light into electrical signals. These electrical signals travel from the retina through the optic nerve to the brain. Then the brain turns the signals into the images you see.
As a bold color that stands out, it's easily noticeable, even from a distance. In addition, red has been shown to increase the heart rate and stimulate the brain, making it a powerful aid in attracting attention. Blue is another notable color for catching the eye.
Colour perception is an exception. Women and men generally perceive colours differently. Women experience the world in warmer colours, for example, and can usually distinguish different shades of red better than men. Men, on the other hand, are better able to perceive poor contrast and rapid movement.
When an object receives light, it absorbs some wavelengths and reflects others.The ones it reflects are the ones we see as color. A green object absorbs all wavelengths except those of the green spectrum. A white object reflects almost all and a black absorbs almost all.
When we look at an object, light is reflected from it into our eyes, which enables us to see. Light enters through the cornea, which acts like a window at the front of the eye. The amount of light entering the eye is controlled by the pupil, which is surrounded by the iris – the coloured part of the eye.
Although complementary colors theory is the most up-to-date, the trichromatic theory and opponent process theory help account for the complexity of color vision. The trichromatic theory explains how the three types of cones detect different light wavelengths.
There are two types of photoreceptors: rods and cones. Rods help you see in low light and around your central field of view (your peripheral vision). They don't help you see in color, only in black and white. Cones are the part of the eye that lets you see colors.
Eye color is directly related to the amount of melanin in the front layers of the iris. People with brown eyes have a large amount of melanin in the iris, while people with blue eyes have much less of this pigment.
“Every colour that people see is actually inside their head … and the stimulus of colour, of course, is light.” As light pours down on us from the sun, or from a lightbulb in our home, objects and surfaces absorb some wavelengths of light and reflect others.
Phosphenes are those images of light or color that you can see while your eye is closed. This can happen when you rub your eyes or when you cough. It can also be a signal that you have a more serious condition, like head trauma.
If you look at his/her outer ear(helix, antihelix, tail helix), it will show you the true colour. So in general ear could help you find the true and natural colour of yours:) Many people get darker as they get older due to built up sun exposure.
