Abstract: Today, advancement in microelectronic technologies, high definition displays (HD), high quality digital imaging systems redefining our world of vision. Microsoft and HP developed sRGB colour space which covers approximately 35% of CIE colour gamut to communicate well via different displays, digital imaging systems, internet etc. Subsequently ColourMatch RGB, Adobe RGB, Apple RGB, wide gamut RGBs etc. had evolved to meet technical and professional need. Commonly used imaging systems use a three band colour encoding scheme or triplets to represent human visual system. The Red Green Blue (RGB) response highly dependent on the optical filters or sensors characteristics, lighting environment and many a parameters of image capturing devices. Until now their device independent standardization, theoretical conversion error, colorimetric characterization by empirical modelling, validations and most importantly reproducibility provide only mediocre colorimetric accuracy. How safe we are in processing a RGB image or a grey scale in digital domain! We discuss here the fundamental implications.
