Unique Properties of 255

  • 255 is the largest value representable as an 8-bit binary number. 8 bits, otherwise known as a byte, is a very common size for storing "small" values in computer memories, and consequently 255 appears as a bound or an otherwise magic number in many computer-related tasks. For example, 255 is the maximum amount of red, green, or blue that goes into an RGB color, as well as the maximum content of any of the four octets of an IP address
  • 255 is the least odd integer greater than 3 which is not the sum of two distinct powers of two and a prime
