How to get HTML color codes

HTML colors are colors used in designing web pages, and the methods for describing and specifying those colors. Authors of web pages have a variety of options available for specifying colors for elements of web documents. Colors may be specified as an RGB triplet in hexadecimal format (a hex triplet); they may also be specified according to their common English names in some cases. Often a color tool or other graphics software is used to generate color values. (from wikipedia)
