===Gamut===
{{Main|Gamut}}
Every RGB monitor has its own [[color gamut]], bounded in [[chromaticity]] by a [[color triangle]]. Some of these triangles are smaller than the [[sRGB]] triangle, some are larger. Colors are typically encoded by 8 bits per primary color. The RGB value [255, 0, 0] represents red, but slightly different colors in different color spaces such as [[Adobe RGB color space|Adobe RGB]] and sRGB. Displaying sRGB-encoded data on wide-gamut devices can give an unrealistic result.<ref>{{cite web |url=http://regex.info/blog/photo-tech/color-spaces-page2 |title=Digital-Image Color Spaces, Page 2: Test Images |last=Friedl |first=Jeffrey |access-date=2018-12-10 |quote=See For Yourself The Effects of Misinterpreted Color Data }}</ref> The gamut is a property of the monitor; the image color space can be forwarded as [[Exif]] metadata in the picture. As long as the monitor gamut is wider than the color space gamut, correct display is possible, if the monitor is calibrated. A picture that uses colors that are outside the sRGB color space will display on an sRGB color space monitor with limitations.<ref>{{cite web |url=http://www.normankoren.com/color_management.html#Basics |title=Gamut mapping |last=Koren |first=Norman |access-date=2018-12-10 |quote=The rendering intent determines how colors are handled that are present in the source but out of gamut in the destination |archive-url=https://web.archive.org/web/20111221111848/http://www.normankoren.com/color_management.html#Basics |archive-date=2011-12-21 |url-status=dead }}</ref> Still today, many monitors that can display the sRGB color space are not factory nor user-calibrated to display it correctly. [[Color management]] is needed both in [[electronic publishing]] (via the Internet for display in browsers) and in [[desktop publishing]] targeted to print.
