Color or colour is the visual perceptual property corresponding in humans to the categories called red, green, blue and others. 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. By defining a color space, colors can be identified numerically by their coordinates.Because perception of color stems from the varying spectral 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). – Wikipedia

Pure white light, such as sunlight, is composed of the visible colors. Sir Isaac Newton discovered this in 1666 by passing a beam of light through a prism. The renowned English scientist was 23 years old at the time. He was made to stay home from Cambridge University for over a year because the plague that was sweeping Europe had closed it down. It was during this period that Newton performed his famous spectrum experiments. To alleviate the boredom of quarantine, he punched holes in the curtains of his darkened room to study the effects of light passing through a prism. The light separated into the same progression of colors found in the natural rainbow … continue on pantone.com
We perceive color just as we perceive taste. When we eat, our taste buds sense four attributes: sweet, salty, sour, and bitter. Point at the foods below to discover their unique taste attributes. Similarly, when we look at a scene, our visual nerves register color in terms of the attributes of color: the amount of green-or-red; the amount of blue-or-yellow; and the brightness … continue on Colorotate
Colors are of philosophical interest for two kinds of reason. One is that colors comprise such a large and important portion of our social, personal and epistemological lives and so a philosophical account of our concepts of color is highly desirable. The second reason is that trying to fit colors into accounts of metaphysics, epistemology and science leads to philosophical problems that are intriguing and hard to resolve. Not surprisingly, these two kinds of reasons are related. The fact that colors are so significant in their own right, makes more pressing the philosophical problems of fitting them into more general metaphysical and epistemological frameworks … continue on Stanford Encyclopedia of Philosophy
In the digital world, when we want to talk about a color, precision is required. Saying “Hey, can you make that circle bluish-green?” will not do … continue on Processing
Whats its color is an image-color processing utility that will evaluate an image and give you the image’s primary and complementary dominant colors of an image, how many visually unique colors are in an image, and the top ten visually unique colors in an image. Extremely useful when creating any type of designs around an image. The more colorful the image, the better the results. Results will display your image on the best suited background for that image. - whatsitscolor
15 Free Color Tools and Palette Generators When it comes to design, color is one of the hardest issues to overcome as there is a huge selection and you just get lost in choosing the right one for your piece of art. It is well-known that color is an important factor that might decide the success of your design and you’d better pay more attention to it before deciding on which color you should choose. If we are talking about web-design – we all know that color choice is critical – we have to pick something that is pleasant for the eye and there definitely should be a contrast between the background color and the content. Thus a palette of colors would be useful, if you want to use certain colors but not be out of track too much so that they wouldn’t match …
Color plays a vitally important role in the world in which we live. Color can sway thinking, change actions, and cause reactions. It can irritate or soothe your eyes, raise your blood pressure or suppress your appetite. When used in the right ways, color can even save on energy consumption. As a powerful form of communication, color is irreplaceable. Red means “stop” and green means “go.” Traffic lights send this universal message. Likewise, the colors used for a product, web site, business card, or logo cause powerful reactions.

Complementary colors are pairs of colors that are of “opposite” hue in some color model. The exact hue “complementary” to a given hue depends on the model in question, and perceptually uniform, additive, and subtractive color models, for example, have differing complements for any given color.
A rainbow is an optical and meteorological phenomenon that causes a spectrum oflight to appear in the sky when the Sun shines on to droplets of moisture in theEarth’s atmosphere. It takes the form of a multicoloured arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.

A great author once describes a Rainbow as “one of the most spectacular light shows observed on earth” and we also feel the same. Technically, A rainbow is an optical and meteorological phenomenon that causes a spectrum of light to appear in the sky when the Sun shines onto droplets of moisture in the Earth’s atmosphere.
Why Should Engineers and Scientists Be Worried About Color?
Modern systems for creating visualizations have evolved to the extent that you can create meaningful representations of your data. However, the process is typically ad hoc, and you often must spend many iterations to create the “right” visualization. A framework for rule-based guidance can improve your effectiveness in visualization by assistance with two types of representation choices. One concerns domain-independent factors, such as ensuring that data content is reflected in images and that perceptual artifacts are not erroneously interpreted as data features. A second type concerns task-dependent factors. For example, different advice on representation is required depending on whether the goal of visualization is exploration or presentation.
