As many of the connectors look very similar, particularly to a novice PC user, the colour-coding of connectors and ports makes it far easier for people to connect peripherals to the correct ports on a PC. This colour code was gradually adopted by almost all PC and motherboard manufacturers. Some of the colour codes have also been widely adopted by peripheral manufacturers.
