How many hexadecimal colors are there?
16,777,216 unique combinations
Not too many people know that web colors may be specified as an RGB triplet or in hexadecimal format. It is interesting to know that when computers name a color, they use a so-called hexadecimal code that most humans gloss over: 24-bit colors. Imagine there are 16,777,216 unique combinations of exactly six characters made from ten numerals and six letters, preceded by a hash mark. Needless to say, hex colors represent a must have for all the computer specialists (designers).
