Amount of red, green, and blue light required. Colours are also often described using a word of. Six hexadecimal digits, where each pair of digits. Colour representation and storage there are 256 values between 0 and 255 there are also 256 possible values for a pair of (i. e. , 2) hexadecimal digits. Understanding the significance of these value requires a basic understanding of computer architecture. Computer architecture abstraction as previously discussed, electronic devices typically communicate using machine languages we can ignore the semantics of these languages (for the moment) and focus on the alphabet. Data representation and storage an alphabet is a standard set of symbols for. Communicating, exemplified by the ten symbols in the hindu-arabic numeral system:
