Hewlett-Packard and Microsoft designed sRGB to match the color gamut of consumer-grade CRTs " "from the 1990s. sRGB is the standard color space for the world wide web and is still the best " "choice for exporting images to the internet.

" "Printer color gamuts can easily exceed the sRGB color gamut in cyans, greens, and yellow-greens. Colors from interpolated " "camera raw files also often exceed the sRGB color gamut.
