What is color?

Question

I'm looking for a technical/scientific explanation. A little more than it's just light. Thanks.

Answer 1

It is the wavelength and frequency of the light beam.

Answer 2

Of course, not all creatures can see color and many humans are color blind. The normal human eye at the center (fovea) has three different type cones that are sensitive to three separate ranges of light wavelengths. When a photon of the right wave length strikes the right cone a chemical reaction sends an impulse to the brain. The brain interprets the input from cones at a point on the retina to perceive pure colors or mixtures of colors.

Answer 3

The colour of something is dictated by the molecular structure of its pigments.

Take, for example, something painted red. The paint contains chemicals that have been chosen due to their molecular structure. This is the pigment. Light hits these pigment molecules, causing the bonds between atoms within the molecule to vibrate in a certain way. Some of the light wavelengths are absorbed as a result, and the light wavelength that is not absorbed (ie. reflected) happens to be the wavelength that appears "red".

Answer 4

The light we see in something is the wavelength of light from the sun that is not being absorbed by the object. One example of this is leaves, leaves are green when alive because they absorb all other light wavelengths from the sun except green in order to preform photosynthesis. Therefore, when leaves die, they do not absorb any more light and can be a variety of colors.

Answer 5

Aspect of any object that may be described in terms of hue, brightness, and saturation. It is associated with the visible wavelengths of electromagnetic radiation, which stimulate the sensor cells of the eye. Red light has the longest wavelengths, while blue has the shortest, with other colours such as orange, yellow, and green between. Hue refers to dominant wavelengths. Brightness refers to the intensity or degree of shading. Saturation pertains to purity, or the amount of white light mixed with a hue. The colours red, yellow, and blue, known as primary colours, can be combined in varying proportions to produce all other colours. Primary colours combined in equal proportions produce secondary colours. Two colours that combine to form white light are said to be complementary.

Answer 6

It's the reflection of light upon materia.
So when a light beam/ray hits an object it will be reflected so that we can see it. More or less a change in direction of some (or all/most) of the energy.

Answer 7

Color (or colour, see spelling differences) is the visual perceptual property corresponding in humans to the categories called red, yellow, white, etc. Color derives from the spectrum of light (distribution of light energy versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. Color categories and physical specifications of color are also associated with objects, materials, light sources, etc., based on their physical properties such as light absorption, reflection, or emission spectra.

Typically, only features of the composition of light that are detectable by humans (wavelength spectrum from 400 nm to 700 nm, roughly) are included, thereby objectively relating the psychological phenomenon of color to its physical specification. Because perception of color stems from the varying sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantified by the degree to which they stimulate these cells. These physical or physiological quantifications of color, however, do not fully explain the psychophysical perception of color appearance.

The science of color is sometimes called chromatics. It includes the perception of color by the human eye and brain, the origin of color in materials, color theory in art, and the physics of electromagnetic radiation in the visible range (that is, what we commonly refer to simply as light).

Answer 8

It is the wavelength and frequency of the light beam that reflect from an object

Answer 9

Color is an abnormal pigmet in one or more objects that certain spectrums of light catch on to.

Answer 10

color of an object depends on the wavelenth of the visible lightwhich our eye receives from the object.each color depends upon a certain range of wavelengths of visible part of the spectrum of e.m radiationto which human eye is sensitive.
