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.
Note that the colors depicted depend on the color space of the device on which you are viewing the image, and therefore may not be a strictly accurate representation of the color at a particular position, and especially not for monochromatic colors.
Colors are produced when a material is scored with fine parallel lines, formed of one or more thin parallel layers, or otherwise composed of microstructures on the scale of the color's wavelength.

 RGB color model - Biocrawler   (Site not responding. Last check: 2007-11-04)
The RGB color model utilizes the additive model in which red, green, and blue light are combined in various ways to create other colors.
One common application of the RGB color model is the display of colors on a cathode ray tube, liquid crystal display, or plasma display, such as a television or computer's monitor.
Colors used in web design are commonly specified using RGB; see web colors for an explanation of how colors are used in HTML and related languages.

The mixture of ideal CMY colors is subtractive (Cyan, Magenta, and Yellow printed together on white result to fl).
However the color a person sees on a computer screen is often slightly different from the color of the same object on a printout since CMYK and the RGB color model used in computer monitors have different gamuts.
RGB color is made by the emission of light (additive color) whereas CMYK works by the absorption of it (subtractive color).

Processes called under color removal, under color addition, and gray component replacement are used to decide on the final mix, so that different CMYK recipes will be used depending on the printing task.
However, the color seen on a computer screen is often different from the color of the same object on a printout since CMYK and RGB have different gamuts.
However, conversion of CMYK colors in general to RGB colors is not invertible; that is, given a CMYK color which is converted to RGB, performing the former conversion may not give the original CMYK color.

The RYB color model is used mostly with traditional artistic and painting concepts, and rarely used outside of paint-pigment mixing.
For all computer-based color, a wheel based on the RGB model is used; this encompasses the CMY model as well since cyan, magenta, and yellow are the secondary colors for red, green, and blue.
Adding a complementary color to a color on the canvas is the traditional technique for making shadows, as well as for choosing a balance of color overall, so that the eye does not tire from an overuse of red, for example.

 RYB color model - Wikipedia, the free encyclopedia
RYB uses pigments, which are not added, and thus combining colors using the RYB color system will result in a darker color.
The RYB color theory has become heavily used by all kinds of artists, and has thus been heavily established as the norm despite its inaccuracies, which are generally either overlooked because of its popularity or simply unnoticed.
The reason that the problems with this model are commonly unnoticed is because modern artists combine hundreds of colors and shades in order to produce their desired pigment, not just red, yellow and blue.

 RGB color model - Wikipedia, the free encyclopedia
The RGB color model is an additive model in which red, green and blue (often used in additive light models) are combined in various ways to reproduce other colors.
These three colors should not be confused with the primary pigments of red, blue and yellow, known in the art world as "primary colors".
The RGB color model itself does not define what is meant by "red", "green" and "blue", and the results of mixing them are not exact unless the exact spectral make-up of the red, green and blue primaries are defined.

 The RYB Color Wheel and how colors relate to each other.
It has Primary Colors of Red, Yellow and Blue, Secondary Colors of Orange, Green, and Purple (which are created by mixing the Primary Colors in equal amounts), and six Tertiary Colors which are created by mixing a Primary and a Secondary Color.
This model is largely used for traditional reasons because Red and Blue are approximations for Magenta and Cyan respectively.
The colors Red, Yellow and Blue are the Primary colors of the color wheel.

 Color theory - Wikipedia, the free encyclopedia
The RYB primary colors became the foundation of 18th century theories of color vision, as the fundamental sensory qualities that are blended in the perception of all physical colors and equally in the physical mixture of pigments or dyes.
On this basis the quantitative description of color mixture or colorimetry developed in the early 20th century, along with a series of increasingly sophisticated models of color space and color perception.
Color theory has not developed an explicit explanation of how specific media affect color appearance: colors have always been defined in the abstract, and whether the colors were inks or paints, oils or watercolors, transparencies or reflecting prints, computer monitors or cinemas, was not considered especially relevant.

This RYB color model has been engraved in our brain, and the various combinations derived from different RYB formulas have a profound effect on us psychologically.
You may notice that the colors that are most harmonious, or complementary, are NOT across from each other on the RGB color wheel.
Another issue is that the cardboard color wheel we traditionally use to choose RYB color is made of printed inks.

Why is it, that in art class you learn that the three primary colors are red, yellow and blue, and in science, the three primary colors are red, green and blue.
When you went to school you learnt that the three primary colors are red, yellow and blue, and now that you are involved with the web, the three primary colors are red, green and blue.

 Old Jewel Painter's Picker
Well, while you can't mix colors in RYB on screen in most programs, you can still design using the now-classic RYB color model with a variety of tools, including a relative newcomer called Painter's Picker from Old Jewel Software.
While computers have forced artists to shift from RYB to RGB, attempts have been made in recent years to provide those working in digital media with tools for creating color schemes based on Itten's model.
(Itten, by the way, didn't actually "invent" the RYB wheel but did make it the de facto standard in design by developing theories about color relationships based on this model.) The most comprehensive of these tools is, no doubt, Color Theory, distributed by http://www.digitalanarchy.com.

 YIQ - The real meaning from Timesharetalk wikipedia   (Site not responding. Last check: 2007-11-04)
YIQ is a color space, formerly used in the NTSC television standard.
The YIQ representation is sometimes employed in color image processing transformations.
For example, applying a histogram equalization directly to the channels in an RGB image would alter the colors in relation to one another, resulting in an image with colors that no longer make sense.

 YIQ   (Site not responding. Last check: 2007-11-04)
YIQ is the color space used in the NTSC television standard.
Thus less bandwidth is required for Q than for I. Broadcast NTSC limits I to 1.3 MHz and Q to 0.5 MHz, which keeps the bandwidth of the overall signal down to 4.2 MHz.
This formula approximates the conversion from the RGB color space to YIQ.

 [No title]
Many people consider this model to be completely wrong, but it is still taught in many schools as the primary color model.
For example, Complementary colors (colors on oposite sides of the color wheel) are completely different between the two models.
Also note that the RYB model does not represent cyans or magentas very well, since they are neither primary or secondary colors, and even getting close requires the addition of white, so the saturation level is wrong.

Color Theory is a digital color wheel that intelligently finds harmonious color combinations using traditional Red-Yellow-Blue (RYB) color space, rather than the Red-Green-Blue (RGB) color space used by computers.
Color Theory includes all 20 of Professor Itten's traditional color formulas, as well as primary, secondary, tertiary, pastel, neutral and clash schemes.
This is important because Itten's color theories, which are taught in every Color Design class, don't work when used with an RGB color model.
