xvYCC

(EXtended-gamut YCC) A color space from the IEC with 1.8 times as many colors as sRGB. Also called "x.v.Color," xvYCC was introduced in 2005 to match the wider color gamut of modern HDTV sets. Whereas sRGB provides a portion of the color spectrum, xvYCC can display every color the human eye can absorb. See sRGB.



sRGB

(Standard RGB) A color space defined by HP and Microsoft for displaying images on the Internet. Based on the video capture profile in the broadcast TV standard (see ITU-R BT.601), many devices, including scanners and digital cameras, default to using sRGB. It was developed in the mid-1990s to provide a consistent color model for CRTs without the overhead of embedding an ICC color profile in the image.

sRGB and Apple RGB are close in color gamut, but both have a much smaller gamut than Adobe RGB, which is closer to the range of color printers. See Adobe RGB, xvYCC and ICC profile.
