Whether you are designing a sophisticated application or just your Facebook page, it is often necessary to know the hexadecimal value of a specific color. That Hex value is one of the most obscure numbers you will ever have to discover, especially if you do not have the proper tool.

As a service to our members, we have published just such a tool — the TechRepublic Color Code Converter.

Click the color you are interested in, and the tool will return the hexadecimal value. With that hex number you can code HTML or CSS or whatever asks for it to display the precise combination of red, green, blue you want. Sure, it is a simple little tool, but it works and it’s free. Give it a try.
