Colour Space.

Colour Space:

Colour space, simply describes the wide range of colours, that a camera can see when taking a photo, a printer can print, or a monitor can display. Colour space can also be known as “Colour model”, and within colour space a range of colours can be created by using the primary colours of pigment.  There are a variety of colour spaces such as, RGB, CMY, HSV etc. RGB (Red, Green, Blue) is a colour space which uses red, green and blue to elaborate a colour model. An RGB format can be interpreted as “all possible colours”.  YUV, the 'Y', determines the brightness of the colour which can also be known as “luma” or “luminance”,the U and V components determine the colour itself (the chroma). HSV (Hue, saturation and value) is a colour model that describes colours (hue or tint) depending on their shade, (saturation or amount of grey) and brightness (value or luminance).  Along with this is another colour space which is,Grey-scale. Grey-scale is a range of shades of grey, without apparent colour. The darkest possible shade within grey-scale is black, and the lightest possible shade is white.
