What are HEX colours and how to use them

Hex or Web colours are colours used in displaying web pages, and the methods for describing and specifying those colours. Colours may be specified as an RGB triplet or in hexadecimal format (a hex triplet). They may also be specified according to their common English names in some cases. Often a colour tool or other graphics software is used to generate colour values. In some uses, hexadecimal colour codes are specified with notation using a leading number sign (#).  A colour is specified according to the intensity of its red, green and blue components, each represented by eight bits. Thus, there are 24 bits used to specify a web colour, and 16,777,216 colours that may be so specified.
