Visible light lies in the 400 and 700 nm range of
White light - Composed of many colors, essentially all of the visible colors in the visible range with equal intensities of each wavelength. Isaac Newton showed that white light could be split into all colors of the rainbow by passing through a prism.
Visible light appears to be split up into three predominant bands of light, red, green and blue. This results from how the human eye perceives light in terms of red, green and blue.
Thus, these are called the primary colors of light. Balanced amounts of R, G and B produce white light. Computer monitors and TV screens use RGB to display color.
Additive Color Treory
White light is the sum of red, green
Additive Color Treory
White light is the sum of red, green
Blue + Green = Cyan
Red + Blue = Magenta
Green + Red = Yellow
Combining in unequal proportions yields new colors. Essentially all perceivable colors can be represented by different amounts of RGB. RGB is usually the native color model used by computers and is also used on most desktop scanners.
Subtractive Color Theory
Secondary colors are used as subtractive primaries, Cyan,
Subtractive Color Theory
Secondary colors are used as subtractive primaries, Cyan,
Cyan + Yellow = Green
Cyan + Magenta = Blue
Magenta + Yellow = Red
Cyan + Magenta + Yellow = Black

In the printing industry in the
manufacture of high-quality reproductions of proofing is to obtain images within the gamut of real synthesis of the printed (in color reproduction) and indicates the suitability of the content of the file for output. To do this all the more widely used standard printing systems, such as ink-jet printers (Figure 75, four-lane A4) or dye-sublimation printer (Fig. 71, 2-page format) in combination with high-performance color management system.
