| the color “space” or document type which is defined by three channels of red, green and blue produced by the color monitor. It is created by combining different intensities of each of the three colors. This type of color producing is called “additive primaries” because the light of the monitor display is added together to make the color you need. Most monitors have a “gamut”, or range, of 16.7 million colors. If you mix the colors you’d get white. |

| the color “space” or document type which is based on the absorption and reflection of light. Usually this process is used mostly in printing such as printing presses or tshirt printing. Four “process” inks – cyan (close to blue), magenta (close to red), yellow and black (called the “subtractive primaries”) are used in varying combinations and percentages to produce a range of printable colors in most commercial printing. A CMYK file has four color “channels” one for each of the subtractive primary. Why is the letter “k” used for black? So that it is not confused with the name “Blue” which is not used in this mode. If you mixed all the colors you would get black. |
