Colour Space:

 A colour space is a method by which we can specify, create and visualize colour. We usually define a colour by its  brightness, hue and colourfulness. A computer needs the colours red, green and blue to recognize an image and also to process that information. A printing press may produce a specific colour in terms of the reflectance and
absorbance of cyan, magenta, yellow and black inks on the printing paper.


Different colour spaces are better for different applications, for example different equipment has
limited factors that dictate the size and type of colour space that can be used.
