Definition: Adobe RGB

A color space defined by Adobe in 1998 that enables images edited in RGB to translate accurately to most color printers (CMYK printers). The Adobe RGB color model has a much greater color gamut than sRGB and Apple RGB, but not as large as CIE Lab. Adobe RGB colors are designated in "RGB triplets" from 0 to 1; for example, black is 0,0,0 and white is 1,1,1. See sRGB, CIE Lab and RGB.
