sRGB is an RGB (red, green, blue) colorspace, for use on monitors, printers, and the World Wide Web. It was initially proposed by HP and Microsoft in 1996[2] and became an official standard of the International Electrotechnical Commission (IEC) as IEC 61966-2-1:1999.[1] It is the current standard colorspace for the web, and it is usually the assumed colorspace for images that do not have an embedded color profile.
The sRGB standard uses the same color primaries and white point as the ITU-R BT.709 standard for HDTV,[3] but a different transfer function (or gamma) compatible with the era's CRT displays,[4] and assumes a viewing environment closer to typical home and office viewing conditions. Matching the behavior of PC video cards and CRT displays greatly aided sRGB's popularity.
