Computing
CSS color codes are often given in hexadecimal using six digits, but can be given in duotrigesimal using only three digits. Using base 32 has risen in popularity due to its compact format. Logically, because the color system used is RGB, which separates the hexadecimal values into groups of two digits, base 32 makes more sense to use, as each component is represented by exactly one character. Base32 is an encoding scheme using base 32.
