  RGB
RGB is played using three of the standard four stashes in an Icehouse set, and a chessboard.
Remember, the RGBs are a primitive people.) If one of your Male stacks is directly adjacent to one of your Female stacks, and both of those stacks still have their Blue (Creation) layer, you may take a turn to place a small stack on the board.
The balance between the two sides in RGB is a bit tricky.

 A Standard Default Color Space for the Internet - sRGB
The three major factors of this RGB space are the colorimetric RGB definition, the equivalent gamma value of 2.2 and the well-defined viewing conditions, along with a number of secondary details necessary to enable the clear and unambiguous communication of color.
RGB spaces are native to displays, scanners and digital cameras, which are the devices with the highest performance constraints
The definitions for RGB given in equations 1.1 to 1.3 are based on the colorspace's respective viewing environment.

 RGB
The New York City Rent Guidelines Board (RGB) is a nine member board, appointed by the mayor, to set rent adjustments for the city's one million rent stabilized apartments.
As a result, for decades the RGB has not acted to preserve affordability when it comes to setting rent adjustments.
The RGB starts meeting in March (all meetings are, by law, open to the public), publishes research reports prepared by the staff, and holds a preliminary vote in May. Public hearings are held in June followed by the vote on the final guidelines.

 What About ProPhoto RGB? - Photo Tips @ Earthbound Light
In addition to the shapes outlining the gamut for sRGB and Adobe RGB, I have added a white line showing the extent of ProPhoto RGB's gamut as well as an indication of the typical gamut of an Epson desktop printer on glossy paper (the gamuts of matte papers tend to be somewhat smaller).
Adobe RGB can still clip some very saturated yellows but does cover all the greens, and green is a very important color being in the middle of the visual spectrum and very prevalent in nature.
Just as Adobe RGB and sRGB contain the same number of colors as dictated by the limitations of how they are represented in 8-bit and 16-bit mode, ProPhoto too has to live within what the numbers are capable of.

 Webopedia: The Science of Color
Unlike the primary colors of pigment, the primary colors of light are red, green (not yellow) and blue, commonly referred to as RGB.
RGB is an additive color system, which means that color is added to a fl background.
To reproduce color on the paper, transparent pigments (cyan, magenta and yellow) are used to filter out the RGB wavelengths in various combinations.

 Graphics Color Models
In the RGB model notice that the overlapping of additive colors (red, green and blue) results in subtractive colors (cyan, magenta and yellow).
In the 24-bit RGB color model there are 256 variations for each of the additive colors of red, green and blue.
In the RGB color model, colors are represented by varying intensities of red, green and blue light.

 What is RGB? - a definition from Whatis.com
RGB (red, green, and blue) refers to a system for representing the colors to be used on a computer display.
In the Hypertext Markup Language (HTML), the color for a page background or text font is specified by an RGB value, expressed with six digits in hexadecimal format.
In creating Web pages, the number of RGB values that are recommended for use is considerably reduced - first, by the fact that many displays can handle only 256 colors and, secondly, because PC and Mac Web browsers handle 40 of these 256 colors slightly differently.

  RGB color model - Wikipedia, the free encyclopedia
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 a computer's monitor.
When written, RGB values in 24 bpp, also known as Truecolor, are commonly specified using three integers between 0 and 255, each representing red, green, and blue intensities, in that order.
Instead, video RGB uses a convention with scaling and offsets such that (16, 16, 16) is fl, (235, 235, 235) is white, etc. For example, these scalings and offsets are used for the digital RGB definition in CCIR 601.

 RGB color space - Wikipedia, the free encyclopedia
RGB is a convenient color model for computer graphics because the human visual system works in a way that is similar - though not quite identical - to an RGB color space.
As of 2004, sRGB is by far the most commonly used RGB color space, particularly in consumer grade digital cameras, because it is considered adequate for most consumer applications, and its design simplifies previewing on the typical computer display.
RGB spaces are generally specified by defining three primary colors and a white point.

 Color space - Wikipedia, the free encyclopedia
For example, Adobe RGB and sRGB are two different color spaces, both based on the RGB model.
RGB uses additive color mixing, because it describes what kind of light needs to be emitted to produce a given color.
HSV is a transformation of an RGB colorspace, and it's components and colorimetry are relative to the RGB colorspace from which it was derived.

 Color Schemes (CMYK & RGB)
RGB is the normal color scheme used in computer graphics, while CMYK is the standard for printing color images.
RGB color is called additive because colors throughout the spectrum are created by adding varying intensities of red, green, and blue light to fl (which on a computer screen equals no light).
When RGB light strikes an object, the amount of cyan, magenta and yellow in the object's pigmentation affects how much light is reflected back (it's the reflected light that we see).

 RGB color model - Wikipedia, the free encyclopedia   (Site not responding. Last check: )
The RGB color model is an additive color 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 or liquid crystal display such as a television picture tube or a computer's monitor.
The RGB color model for HTML was formally adopted as an Internet standard in HTML 3.2 (http://www.w3.org/TR/REC-html32), however it had been in use for some time before that.

 Scanning B&W negative (why scan in RGB ?)
The file size of an RGB scan is so much larger than gray scale that I would like to scan my negatives in gray scale if there is no clear advantage to an RGB scan.
When you convert from RGB to gray scale or bandw, you eliminate 2 of the 3 chanels (usually leaves the red one) and you finish with an image with 3MB.
I used to scan in RGB mode, but then realized that there was basically no difference in grain or tonality between the individual channels in my scans, meaning that the extra "bit depth" was being wasted.

 Keohi HDTV - Learn About - Definitions - RGB vs YPrPb
RGB is theoretically better but at the same more expensive and was impractical for over the air broadcasting.
RGB (which VGA is) is superior for computer data, but that only has to travel a few feet from PC to monitor.
If the TV takes RGB, converts it to Y/Pb/Pr for intermediate processing (mine does ^@#%%$!) and then back to RGB, there is more of a chance there will be some idiosyncrasy compared with RGB straight to the picture tube that a regular computer monitor does.

 RGB and HSL Colour Space Conversions
The classic RGB colour space used in GDI+ is excellent for choosing or defining a specific colour as a mixture of primary colour and intensity values but what happens if you want to take a particular colour and make it a bit lighter or a bit darker or change its saturation.
The conversion of HSL to RGB is a well known algorithm that you can find in numerous places on the web.
Oddly enough, down in the bowels of the ControlPaint class, RGB to HSL is employed when you use the ControlPaint.Light(…) or ControlPaint.DarkDark(…) methods but also unfortunately the scaling of the Light, Dark and DarkDark settings are, to say the least, brutal and offer no finesse.

 RGB & CMY
For this reason, the example of RGB filters of figure 1 is rather characteristic since the filter B and the filter G overlap just at the wavelenth of the significant line [OIII] at 500.7 nm.
The examination of figure 1 shows that with RGB combination the line [OIII] is observed at the same time with the B filter and the G filter, so the signal of the line in these two bands is thus added at the time of the constitution of the true colors image.
Simplest is to observe star of a Solar type through filters RGB and CMY, and to determine a set of coefficients to apply to the pixels of components RGB channel in such a way that the standard star is restored to white on the screen.

 Internet DTP Colour Intro tutorial
RGB colour is all around us in the form of light, and is referred to as the Additive colour system.
So total darkness would be described in RGB values as R=0,G=0 and B=0, and all visible light would be described as R=255, G=255 and B=255.
Any value of Red Green or Blue is always between 0 and 255 which allows for a maximum of 256 values because to a computer, 0 is indeed a value whereas 0 means nothing in human terms.
