Detailed Description

Class representing colour.

Remarks: Colour is represented as 4 components, each of which is a floating-point value from 0.0 to 1.0.

: The 3 'normal' colour components are red, green and blue, a higher number indicating greater amounts of that component in the colour. The forth component is the 'alpha' value, which represents transparency. In this case, 0.0 is completely transparent and 1.0 is fully opaque.
