How HTML Color Codes are generated? Posted on January 24, 2014 by Aleksandar Gichevski (G+)

HTML color codes are hexadecimal triplets that represent red, green and blue color. In this post I will explain the theory about HTML Color codes, how their format is created and which of them are defined in HTML and CSS color specification.

How HTML Color Codes are generated?

HTML color code format is symbol '#' and 6 letters or numbers. These numbers are written in hexadecimal numeric system. First 2 symbols represent the intensity of red color between 00 (which is least) and FF (most intense). Second 2 symbols (third na fourth) represent the intensity of green color while last 2 symbols (fifth and sixth) represent the intensity of blue color. Mixing these 3 basic colors we can create any color we need.
