about

When I originally made 'Colour Space' I was working in a profession (digital cinema mastering) that involved the use of this process.

Here is Wikipedia's definition of 'Colour Space'... Confused ? So was I :)

''A colour space is a specific organization of colours. In combination with physical device profiling, it allows for reproducible representations of colour, in both analog and digital representations. A colour space may be arbitrary, with particular colours assigned to a set of physical colour swatches and corresponding assigned names or numbers such as with the Pantone system, or structured mathematically, as with Adobe RGB or sRGB. A colour model is an abstract mathematical model describing the way colours can be represented as tuples of numbers (e.g. three tuples in RGB or four in CMYK), however a colour model with no associated mapping function to an absolute colour space is a more or less arbitrary colour system with no connection to any globally understood system of colour interpretation. Adding a specific mapping function between a colour model and a reference colour space establishes within the reference colour space a definite "footprint", known as a gamut, and for a given colour model this defines a colour space. For example, Adobe RGB and sRGB are two different absolute colour spaces, both based on the RGB colour model. When defining a colour space, the usual reference standard is the CIELAB or CIEXYZ colour spaces, which were specifically designed to encompass all colours the average human can see.

Since "colour space" is a more specific term, identifying a particular combination of colour model and mapping function, it tends to be used informally to identify a colour model, since identifying a colour space automatically identifies the associated colour model, however this usage is strictly incorrect. For example, although several specific colour spaces are based on the RGB colour model, there is no such thing as the singular RGB colour space''
