  colorspace-faq -- FAQ about Color and Gamma
Color is the perceptual result of light in the visible region of the spectrum, having wavelengths in the region of 400 nm to 700 nm, incident upon the retina.
The colors that can be mixed from a particular set of CMY primaries cannot be determined from the colors of the primaries themselves, but are also a function of the colors of the sets of combinations of the primaries.
HSB and HLS were developed to specify numerical Hue, Saturation and Brightness (or Hue, Lightness and Saturation) in an age when users had to specify colors numerically.

The color information of the entire image was then represented as a set of n color vectors, where n is the number of pixels in the original image.
The cylindrical and conical HSB interpretations are very similar, the difference being that in the conical interpretation, the saturation depends on the brightness of the color.
The brightness of its clusters were extremely accurate, but overall, the colors tended to be unrealistically gray and muddy.

  What were early studies of color?
He recognized that the colors comprising white light are "refracted" (bent) by different amounts and he also understood that there is no "colored" light, the color being in the eye of the beholder.
Being a painter, mixing of yellow and blue pigments to obtain green color was so familiar to him that he had refused to recognize green as a pure color.
The four prime colors red, green, blue and yellow are positioned according to their polarity as poles of two perpendicular axes.

 Color Spaces
Describes a color space that can be defined using the full gamut of human vision, as defined by a standard observer, independent of the color rendering capabilities of any specific device.
These color spaces are limited by the gamut, or range of colors, that a particular device is capable of recording or producing.
Note that in the CIE color space diagrams the spectral locus is horseshoe shaped and the wavelengths are not linearly spaced around the locus.

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.

The most intuitive model of color, HSB defines a color as a combination of: its Hue, the position around a 360 degree color wheel; its Saturation, the "purity" of the color; and its Brightness, the lightness or darkness of the color.
Color choices that you make in the selection fields will only affect the component that is selected in the pull-down menu.
Avoid colors saturated over 80%, and certain color combinations where the hue is very far apart should be kept to even lower saturations.

 HSV color space - Wikipedia, the free encyclopedia
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.
Given a color (H, S, V) in HSV color space, there exists a complement (H', S', V') such that when (H, S, V) and (H', S', V') are mixed in equal proportions, the saturation of the resulting color is 0.

 Computer Graphics : Colors
A hue value of 0 indicates the color red; the color green is at a value corresponding to 120°, and the color blue is at a value corresponding to 240°.
A saturation value of 0 (in the middle of a hexagon) means that the color is "colorless" (gray); a saturation value at the maximum (at the outer edge of a hexagon) means that the color is at maximum "colorfulness" for that hue angle and brightness.
The colors were made in Adobe Photoshop in Lab color space and converted to RGB space using the gamma mentioned.

 Custom Windows Forms Controls: ColorPicker.NET
For instance, if you select the green color space component in the RGB color space, the range of values of the green coordinate would be represented by the color slider, and the red and blue coordinates would be represented by the x and y axes respectively, in the color field.
As another example, by selecting the hue color space component, the range of the hue values would be represented by the color slider and the saturation and brightness values would be represented by the x and y axes respectively, in the color field.
When you change the color slider value, there are, at a minimum, four different controls that need to be updated: the color field, the currently selected color window, the active coordinate, and the opposing color space (that is, if an RGB value is changed, the HSB color space needs to be updated).

Color Depth is the number of available colors in a graphic image, represented either as the number of bits per color, or as the number of possible colors in the image's palette.
Saturation is the intensity of the color, from gray to pure color.
The faces of the RGB cube are fully-saturated colors; the gray diagonal of the cube is zero-saturation.

HSB and HLS were developed to specify numerical Hue, Saturation and Brightness (or Hue, Lightness and Saturation) in an age when users had to specify colours numerically.
The usual formulations of HSB and HLS are flawed with respect to the properties of colour vision.
HSB and HSL are not useful for image computation because of the discontinuity of hue at 360 degrees.

The vertical slider is used to adjust the component of the color space selected (in this case, the R in RGB).
This color space, characterized by three variables—L*, a*, and b*—is one in which equal distances in the space represent approximately equal perceptual color differences.
Space can be described by different coordinate systems, and the three most widely used color systems, Munsell, Ostwald, and CIE, describe the color space with different parameters.

 » Image Filter Theatre: HSB Mixer Safe from the Losing Fight: Personal weblog of a Mac geek   (Site not responding. Last check: 2007-10-20)
HSB, aka HSV, is a color space that defines color by three components: hue, saturation, and brightness (sometimes called value).
Saturation is the vibrancy of the color, typically measured from 0 to 100.
The HSB color space is a cone, with the hue running the circumference of the base, saturation running from the center to the edge of the cone, and brightness running the height of the cone.

The line-up of colors from one cube point to the next is often referred to as a "color ramp" since the colors along the way phase gradually from one color to another.
In the CMYK color space the Primary Colors are Cyan, Magenta and Yellow.
When the mix diverges away from primary colors, the result is lighter, darker, or grayer, and the color appears to be somewhere in between the primary colors.

Sometimes the 2 colors were not even fl and white; there were many terminals sold that had either green or amber screens, which either had 2 shades of green or 2 shades of amber.
There were still 16 colors at any one time, but the 16 colors could be thought of as pens, with each pen having a redefinable color.
That is, the 256 combinations that can fit into 8 bits point to a larger color palette, usually from 24-bit color space (8 bits each red, green, and blue).

 CS563: Digital Color
CMY (cyan, magenta, yellow) is the basic color space used when applying colors to media printed on a white background (such as paper).
This color space is useful in printing, where K can be mixed into the CMY inks to produce a much darker fl than could be produced by saturating the paper with ridiculous amounts of cyan, magenta, and yellow.
Luminence is the brightness of the color - the intensity.

For instance, when colors are displayed on a computer monitor, they are usually defined in the RGB (red, green and blue) color space.
This is another way of making the same colors, and red, green and blue can be considered as the X, Y and Z axes.
Another way of making the same colors is to use their hue (X axis), their saturation (Y axis) and their brightness (Z axis).

 Selecting visually different RGB colors
We are used to represent colors as 3 main composants: the Hue (red, green, yellow, ie the rainbow colors), the Luminosity or Brightness (dark, light), and the Saturation (pastel, deep).
For example, the HSB color with maximum B would be white whereas RGB colors red (1,0,0), green (0,1,0) and yellow (1,1,0) would have the same L value.
The HSB color space looks like 2 cones: the lower tip is fl, the upper tip is white, the color wheel is at the middle.

The refractory and/or insulation of boilers, heat treat ovens, refrigerated spaces, driers, ovens and buildings all represent places where the slow and undetected loss of a desired control to the atmosphere can increase operational costs.
The problem may be that the insulation is not where it is supposed to be, and it creates a chimney effect that actually draws in cold air from the outside.
