A lista abaixo mostra a precisão de cores em ordem de qualidade, quantidade e precisão das cores. O filme fotografico, pelicula, bate todos.
Following is a list of representative color systems more or less ordered from large to small color gamut:
* Photographic film is one of the best systems available for detecting and reproducing color. Movie goers are familiar with the difference in color quality between the film projections seen in theaters and the home video versions. This is because the color gamut of film far exceeds that of television.
* Laser light shows use lasers to produce very nearly monochromatic light, allowing colors far more saturated than those produced by other systems. However, mixing hues to produce less saturated colors is difficult. In addition, such systems are complex, expensive, and ill-suited to general video display.
* CRT and similar video displays have a roughly triangular color gamut which covers a significant portion of the visible color space. In CRTs, the limitations are due to the phosphors in the screen which produce red, green, and blue light. Besides the limitations of the device itself, for displaying realistic images, such displays rely on the quality of color sensors, such as those in digital cameras and scanners. Sony has recently introduced a four-color (RGB plus "emerald") color sensor system which may eventually lead to high end video displays with an even larger color gamut. How practical this is remains to be seen.
* Liquid crystal display (LCD) screens filter the light emitted by a backlight. The gamut of an LCD screen is therefore limited to the emitted spectrum of the backlight. Typical LCD screens use fluorescent bulbs for backlights, and have a gamut much smaller than CRT screens. LCD Screens with certain LED backlights yield a more comprehensive gamut than CRTs.
* Television uses a CRT display (usually), but does not take full advantage of its color display properties, due to the limitations of broadcasting. HDTV is far better, but still somewhat less than, for example, computer displays using the same display technology.
* Paint mixing, both artistic and for commercial applications, achieves a reasonably large color gamut by starting with a larger palette than the red, green, and blue of CRTs or cyan, magenta, and yellow of printing. Paint may reproduce some highly saturated colors that can not be reproduced well by CRTs (particularly violet), but overall the color gamut is smaller.
* Printing typically uses the CMYK color space (cyan, magenta, yellow, and black). A very few printing processes do not include black; however, those processes are poor at representing low saturation, low intensity colors. Efforts have been made to expand the gamut of the printing process by adding inks of non-primary colors; these are typically orange and green (see Hexachrome) or light cyan and light magenta. Spot color inks of a very specific color are also sometimes used.
* A monochrome display's color gamut is a one-dimensional curve in color space.
