In particular, sRGB excludes the range of highly saturated colors. However, a look at the xy chromaticity diagram shows that the range of colors that can be expressed using sRGB is narrow. By ensuring that the devices and applications used in the input and output of image data are sRGB compatible, we can reduce discrepancies in color between input and output. In most cases, products like LCD monitors, printers, digital cameras, and various applications are configured to reproduce the sRGB color gamut as accurately as possible. sRGB has established a firm position as the standard in Windows environments. The standard color gamut for personal computers is the international sRGB standard prepared in 1998 by the International Electrotechnical Commission (IEC). An LCD monitor is not capable of reproduction (display) of colors outside its color gamut. The color gamut of an LCD monitor's hardware can be indicated using similar triangles. The ranges corresponding to the sRGB, Adobe RGB, and NTSC standards defining color gamuts appear as triangles connecting their RGB peak coordinates. The areas enclosed in dotted lines represent the range of colors human beings can see with the naked eye. This is a CIE XYZ color system xy chromaticity diagram. For LCD monitors, this means that a product compatible with a color gamut associated with a larger triangle can reproduce a wider range of colors on screen. A larger area inside a triangle is regarded to represent a standard capable of displaying more colors. These triangles show the peak RGB coordinates connected by straight lines. The color gamut defined by each standard is depicted as a triangle on the xy chromaticity diagram. The three standards frequently cited in relation to personal computers are sRGB, Adobe RGB, and NTSC. In the following xy chromaticity diagram, the area shaped like an upside-down "U" surrounded by dotted lines indicates the range of colors visible to human beings with the naked eye. In an xy chromaticity diagram, the colors of the visible range are represented using numerical figures and graphed as color coordinates. Various methods are used to express (diagram) the color gamut, but the common method used for display products is the xy chromaticity diagram of the XYZ color system established by the International Commission on Illumination (CIE). While color imaging devices include a wide range of devices, such as digital cameras, scanners, monitors, and printers, since the range of colors they can reproduce varies, the color gamut is established to make these differences clear and to reconcile the colors that can be used in common between devices. All Rights Reserved.Ī color gamut defines a more specific range of colors from the range of colors identifiable by the human eye (i.e., the visible spectrum). Note: Below is the translation from the Japanese of the ITmedia article "IT Media LCD Monitor Course II, Part 1" published on November 11, 2008. Our hope is that this session will help users better understand the color gamut of LCD monitors and better select, use, and adjust the products. While wide color gamuts are the latest trend in LCD monitors, color gamut is a term that lends itself to misunderstanding. LCD Monitor Course II, which kicks off this session, will address certain points one must know to choose the LCD monitor best-suited to one's needs from the various models available.
