A hex triplet is a six-digit, three-byte number used in HTML, CSS, SVG, and other computer programs, to represent colors. The bytes represent the red, green and blue parts of the color. One byte represents a number in the range 00 to FF, or 0 to 255 in decimal notation. This represents the least (0) to the most (255) intensity of each of the color components. The hex triplet is formed by concatenating three bytes in hexadecimal notation, in the following order:
- Byte 1: red value (color type red)
- Byte 2: green value (color type green)
- Byte 3: blue value (color type blue)
For example, consider the color where the red/green/blue values are decimal numbers: red=36, green=104, blue=160 (a greyish-blue color). The decimal numbers 36, 104 and 160 are similar to the numbers 24, 68 and A0 respectively. The hex triplet is obtained by combining the 6 hexadecimal digits together, 2468A0 in this example.
