Colour Space

Adobe RGB 1998 and sRGB IEC61966-2.1 (sRGB) are two of the most common working spaces used in digital photography.

sRGB is a RGB color space proposed by HP and Microsoft because it approximates the color gamut of the most common computer display devices. sRGB is a RGB color space proposed by HP and Microsoft because it approximates the color gamut of the most common computer display devices. 

Adobe RGB 1998 was designed (by Adobe Systems, Inc.) to encompass most of the colors achievable on CMYK printers, but by using only RGB primary colors on a device such as your computer display. The Adobe RGB 1998 space encompasses roughly 50% of the visible colors specified by CIE.


• RGB or Red, Green and Blue are the primary colours of light, and usually the principal colours we view on a monitor.
• CMYK or Cyan, Yellow, Magenta and Black are primary colours used for all printing techniques.
• Many RGB colours that are viewed on screen cannot be printed to CMYK or vice-versa.
