What is a HTML color code?

A HTML color code is an identifier used to represent a color on the web and within other digital assets. Common color codes are in the forms of: a keyword name, a hexadecimal value, a RGB (red, green, blue) triplet, or a HSL (hue, saturation, lightness) triplet. Different values allow for 16,777,216 potential colors to be chosen.

For example, the color red can be identifier using the following formats:

• red (keyword name)
• #ff0000 (hex)
• (255,0,0) (RGB)
• (0, 100%, 50%) (HSL)

Because there are so many colors to choose from, tools have been created to make the task of selection much simpler. A color picker allows a user to select a color by clicking on visual range of color to pin-point an exact code. A color chart provides a listing of common colors for quick selection.
