  HSV color space - Biocrawler   (Site not responding. Last check: 2007-10-08)
It is a nonlinear transformation of the RGB color space, and may be used in color progressions.
The HSV color space could also be visualized as a cylindrical object; similar to the cone above, the hue varies along the outer circumference of a cylinder, with saturation again varying with distance from the center of a circular cross-section.
The resulting values are in (H,S,V) form, where H varies from 0.0 to 360.0, indicating the angle in degrees around the color circle where the hue is located.

  Color   (Site not responding. Last check: 2007-10-08)
Media that transmit light (such as television) use additive color mixing with primary colors of red, green, and blue which are close to the wavelengths that generate peak responses of the eye's color receptors.
Note that the color experience of a given light mixture may vary with absolute luminosity, due to the fact that both rods and cones are active at once in the eye, with each having different color curves, and rods taking over gradually from cones as the brightness of the scene is reduced.
When producing a color print or painting a surface, the applied paint changes the surface; if the surface is then illuminated with white light (which consists of equal intensities of all visible wavelengths), the reflected light will have a spectrum corresponding to the desired color.

 RGB color space
The RGB color space is an additive color space in which red, green, and blue light are combined in various ways to create other colors.
RGB is known as an additive color space because when light of two different frequencies travel together, from the point of view of an observer, these colors are added to create a new color experience.
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.

 HSL color space - Wikipedia, the free encyclopedia
HSL is similar to HSV but better reflects the intuitive notion of "saturation" and "lightness" as two independent parameters, and is therefore more suitable for use by artists.
In HSL, the Saturation component always goes from fully saturated color to the equivalent gray (in HSV, with V at maximum, it goes from saturated color to white, which may be considered counterintuitive).
In software, a hue-based color model (HSV or HSL) is usually presented to the user in the form of a linear or circular hue chooser and a two-dimensional area (usually a square or a triangle) where you can choose saturation and value/lightness for the selected hue.

The HSV color space could also be visualized as a cylindrical object; similar to the cone above, the hue varies along the outer circumference of a cylinder, with saturation again varying with distance from the center of a circular cross-section.
Such a representation might be considered the most mathematically accurate model of the HSV color space; however, in practice the number of visually distinct saturation levels and hues decreases as the value approaches fl.

 efg's HSV Lab Report
The gray circle is updated in the Hue-Saturation Color Circle to indicate the Saturation level from 0.0 at the circle center to 1.0 at the outer edge.
Complementary colors are in-between: Yellow is at 60 degrees, Cyan is at 180 degrees, and Magenta is at 300 degrees.
HSV is an interesting alternative color space that is very useful in a variety of problems.

 Encyclopedia: HSV color space
Color progressions are ranges of color whose values transition smoothly through a hue, saturation, luminance, or any combination of the three.
Color (US) (colour, internationally) is a sensation which (in humans) derives from the ability of the fine structure of the eye to distinguish three differently filtered analyses of a view.
Structural color is a property of some surfaces that are scored with fine parallel lines, formed of many thin parallel layers, or otherwise composed of periodic microstructures on the scale of the color's wavelength, to make a diffraction grating.

 HSV And H2SV Color Space - ILabWiki
This is a standard representation of HSV color space as a cone.
The primary difficulty with HSV color space (http://en.wikipedia.org/wiki/HSV_color_space) is that Hue (http://en.wikipedia.org/wiki/Hue) is modulus (http://en.wikipedia.org/wiki/Modulo).
We convert HSV to H2SV1 (or H2SV2 etc) by converting Hue which is in radial coordinates 0 - 360 and converting it to Cartesian coordinates The precise coordinate transform is flexible, so long as it is invertible here, we treat r (hue) as falling along a straight line.

All colors descend from the concrete light of whiteness.
The general arrangement of the frequencies of light waves is analogous as in models HLS or HSI, that is: the centre of red color corresponds with the angle of 0 degrees or 360 degrees.
The centre of green color corresponds with the angle of 240 degrees.

 Histogram-Based Color Image Retrieval   (Site not responding. Last check: 2007-10-08)
A color space is defined as a model for representing color in terms of intensity values.
To obtain a good color representation of the image by uniformly sampling the RGB space it is necessary to select the quantization step sizes to be fine enough such that distinct colors are not assigned to the same bin.
In the case that quantization of the color space is not perceptually uniform the cross term contributes to the perceptual distance between color bins.

 Color Space   (Site not responding. Last check: 2007-10-08)
This is a subtractive color space, as more paint pigment is added to the mixture the more light is absorbed and the darker the color becomes, (remember the disappointing dark brown that resulted at the end of our joyous experiments in adding paints together).
The secondary colors are purple (a mixture of blue and red), orange (a mixture of red and yellow), and green (a mixture of yellow and blue).
This emissive color space is based on the primary colors of light perceived by the eye.

This method is well-suited to visualizing the entire HSV color space in a singleobject; however, due to its three-dimensional nature, it is not well-suited to color selection in two-dimensional computerinterfaces.
The HSV color space could also be visualized as a cylindrical object; similar to the cone above, the hue varies along theouter circumference of a cylinder, with saturation again varying with distance from the center of a circular cross-section.
The resulting values are in (H,S,V) form, where H varies from 0.0 to 360.0, indicating the angle in degrees around the color circle wherethe hue is located.

 Information on the HSV colour space
The HSV color space is cylindrical, but usually represented as a cone or a hexagonal cone (hexcone), as displayed in this picture, because this is the subset of the space with valid RGB values.
Thus, the main diagonal of the RGB cube corresponds to the V parameter of the HSV space.
The HSV color space, like RGB, is a device-dependent color space, meaning the actual color you see on your monitor depends on what kind of monitor you are using, and what its settings are.

 Determining the best Color Space for compression   (Site not responding. Last check: 2007-10-08)
Now that we know in each color space which are the components that we can subsample without increasing too dramatically the distortion we need to compare the four color spaces.
Indeed for example the colors of peppers are green and red : one of the opponent colors channel.
For example in a color space in which the interchannel cross correlation is high, information will be coded redundantly and and this will lead to lower compression ratios.

Color, (Colour British English) is the sensation caused by light as it interacts with the eye, brain, and our experience.
The perception of color is also greatly influenced by nearby colors in the visual scene.
Examples of non-spectral colours are the achromatic colors (fl, gray and white), pastel (desaturated) colors such as pink or tan, and magenta.

 Converting Between Device-Dependent Color Spaces :: Color (Image Processing Toolbox)
In the NTSC color space, image data consists of three components: luminance (Y), hue (I), and saturation (Q).
Note In the YIQ color space, I is one of the two color components, not the grayscale component.
The HSV color space (hue, saturation, value) is often used by people who are selecting colors (e.g., of paints or inks) from a color wheel or palette, because it corresponds better to how people experience color than the RGB color space does.

A color model is a specification of a three-dimensional color coordinate system within which each displayable color is represented by a point in that coordinate system.
There are three common color models that are hardware oriented: the RGB (Red, Green, Blue) model used by most color graphics display devices; the CMY (Cyan, Magenta, Yellow) model used by most color printing devices; and the YIQ model used by broadcast television.
Y is the color component of a television signal that is shown on fl-and-white televisions; Y minimizes the effect of two colors appearing different to the human eye but mapping to similar monochrome intensities.

See CIE for the standard representation of color space, where the border is composed of a horseshoe curve representing the pure spectral colors, with a straight line completing the perimeter along the bottom and representing the mixtures of extreme red and blue/violet that give the pure purples.
The same argument applies to complementary colors; for many coordinates in the green area of CIE color space, no complementary wavelength exists, but there is a complementary pure purple.
Other measures of color rendering properties of a light source are: How closely the color appearances of colored samples lit by a given light resemble those of the same samples lit by a reference Planck radiator.
