We will look at the RGB and base 16 concepts (hexadecimal), as
as talking about why computers use the BINARY or base 2 system.
One byte equals two nybbles. One half byte is a nybble and those
4 bits (binary digits) can be expressed with one hexadecimal digit.
The base 16 digits are 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E, and F.
Base 16 F = 15 in base 10 decimal and BR>hexadecimal F = 1111 in base 2 binary.
