As a result, every hue is mirrored in white. In contrast, an item looks black when no light is reflected or reaches the eye. As a consequence, the colors are completely absorbed. Silver is the finest light reflector in the visible spectrum, but not in all spectrums. It does not absorb energy like black so it can be used to transmit light from one place to another.
The color of objects depends on their material composition. Objects made of different materials will reflect light in different ways. For example, a flower consists of many layers of cells that contain pigments that can only be seen under a microscope. These structures cause the flower to reflect red, yellow, and blue light but not green because it is not transmitted through plant tissues. Vegetables and fruits also consist of cells with pigment molecules inside them. When sunlight strikes these substances, some wavelengths are reflected while others are absorbed. This is why vegetables look green and fruits look orange.
Objects that are composed of similar cells but contain different types of pigment molecules will also reflect light in different colors. For example, the stones found in a beach have different colors because they are made up of different materials: sand is silicon dioxide (SiO2), water is hydrogen oxide (H2O), and pebbles are quartz (SiO2).
White objects such as clouds, snow, and paper reflect all colors equally.
When you stare at a white item, you are seeing all of the wavelengths of light reflected back to you. White does not absorb any wavelengths of light. When you observe a dark item, on the other hand, you are actually observing the absence of any light wavelengths being reflected back. Black absorbs all colors of light.
This is why whites appear brighter than blacks. The only way to make a black object appear as bright as a white one would be to increase its exposure time far beyond what humans can perceive. Even with a very short exposure time, a black object will not appear as bright as a white one because there simply isn't enough time for all of the wavelengths to be reflected back into our eyes.
It's also why photographs of people look so much paler when taken in direct sunlight. Your skin absorbs most of the sunlight, which means that only the wavelengths that are transmitted through your skin are reaching the photo sensor. These wavelengths are known as "infrared" because they cannot be seen with the naked eye but are detected by cameras.
Finally, it's why photographs look better when shot in overcast conditions. During sunny days, the light is both visible and invisible wavelengths of light, which makes for too much stimulation if you are trying to take pictures without burning out your retina.
Anything that looks white reflects all wavelengths of light, as demonstrated by shining a white light through a prism. Black is the color with the lowest reflectivity; it is the color of a surface that absorbs all light. Anything that looks black therefore does not reflect light.
The human eye is very sensitive to red, so colors that are close to red, such as pink and orange, tend to look brighter than they are. On a dark night, you can see objects that are several miles away if you gaze into the center of a bright red sunset. The color red is made up of waves of energy traveling at the speed of light (red light). As these waves hit an object they are slowed down and reflected back toward your eyes. If the object is black, then all that reaches your eyes will be the waves of red light. If the object is white, some of the waves will be stopped by the surface and not returned to your eyes. So on a dark night, when you look at a red sunset, you are seeing not only the far-away objects but also those closer to home because their lights have been filtered out by your local sky.
On a clear moonlit night, you can see millions of stars with the unaided eye. The brightest star in the sky is actually a giant planet called "Sun" that lies about 25 trillion kilometers from Earth.
