  RGB World - Understanding Color
Where the blue and green spotlights overlap, the color cyan is produced; where the blue and red spotlights overlap, the color magenta is produced; where the red and green spotlights overlap the color yellow is produced.
A red apple is a good example of subtractive color; the apple really has no color; it has no light energy of its own, it merely reflects the wavelengths of white light that cause us to see red and absorbs most of the other wavelengths which evokes the sensation of red.
Subtractive color starts with an object (often a substrate such as paper or canvas) that reflects light and uses colorants (such as pigments or dyes) to subtract portions of the white light illuminating an object to produce other colors.

  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.
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.
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.

 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.

 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.
For color to be reproduced in a predictable manner across different devices and materials, it has to be described in a way that is independent of the specific behavior of the mechanisms and materials used to produce it.
Color management is a term that describes a technology that translates the colors of an object (images, graphics or text) from their current color space to the color space of the output devices like monitors, printers,...

The format of an HSLA color value in the functional notation is 'hsla(' followed by the hue in degrees, saturation and lightness as a percentage, and an , followed by ')'.
User agents may default the 'flavor' color to the dominant accent color used on the physical machine/mechanism that the user is interacting with (frequently a mouse, keyboard, monitor and computer case, often just a laptop), if the UA is able to retrieve that information from the platform and machine.

 Color Table
Colors can be specified in HTML pages in two waysby using a color name, or by using numbers to denote an RGB color value.
An RGB color value consists of three two-digit hexadecimal numbers specifying the intensity of the corresponding color.
For example, the color value #FF0000 is rendered red because the red number is set to its highest value, FF (or 255 in decimal form).

To specify a color, simply select a value between 0 and 255 for R, G, and B. For example, White is specified by (255, 255, 255), while Black is (0, 0, 0).
To specify the colors for the text and background of your homepages, you need to enter Hex values which represent the RGB values of the colors you like.

 Color Management for Photographers #006 @Digital Outback Photo
Colors that are outside the paper gamut need to be mapped using a "perceptual" rendering intent.
RC is best when only a small portion of colors from the source space will get clipped as the slight compression to the out-of-gamut colors is acceptable and the main body of colors is kept relatively intact.
Perceptual is going to be the better choice when a large portion of colors from the source space are going to get clipped, as more compression is required to “fit” all of the colors in the target space and still maintain smooth tonal gradations.
