Hex color, also known as hexadecimal color, is a way to represent colors using a hexadecimal (base-16) numbering system. It's commonly used in web design, graphics, and computer programming to specify colors for various elements like text, backgrounds, and borders.
In a hex color code, colors are represented using a combination of six characters: numbers 0-9 and letters A-F (case-insensitive). The code starts with a hash symbol (#) followed by six characters that define the intensity of red, green, and blue (RGB) components of the color. Each pair of characters represents one of the RGB components, where 00 is the lowest intensity and FF is the highest intensity. For example:
Hex color codes offer a wide range of colors by allowing 256 levels of intensity for each RGB component (16 * 16 = 256). They are widely used in HTML and CSS for specifying colors in web design and can also be used in various programming languages for graphics and interface design.
