HEXkoodide

HEXkoodide is a term often used in informal contexts to refer to hexadecimal color codes. These codes are a way of representing colors in digital applications, particularly in web design and computer graphics. A hexadecimal color code is a six-digit sequence preceded by a hash symbol (#). These digits are drawn from the hexadecimal number system, which uses digits 0-9 and letters A-F to represent values from 0 to 15.

The six hexadecimal digits are divided into three pairs, each representing the intensity of red, green, and blue light, respectively. The first pair of digits represents the red component, the second pair represents the green component, and the third pair represents the blue component. Each pair can range from 00 (no intensity) to FF (maximum intensity). For example, the code #FF0000 represents pure red, as the red component is at its maximum (FF), while green and blue are at their minimum (00). Similarly, #00FF00 is pure green, #0000FF is pure blue, and #FFFFFF is white (all components at maximum). Black is represented by #000000 (all components at minimum).

The hexadecimal system is used because it is a compact and efficient way to represent color values. Each pair of hexadecimal digits corresponds to an 8-bit number, and three such pairs represent a 24-bit color value, also known as "true color," which can display millions of different colors. This system is widely adopted in HTML, CSS, and various graphics software.
