The UTP Color Code

The UTP color code is a quite complex until you get used to it. There are a total of eight conductor cables. Each of the cables contains four different sets of wires; each set of wires has one solid color and one white wire. The sets of cables are twisted together and should remain twisted with the exception of the top one half inch to ensure Ethernet reliability.

You should always comply with the two wiring standards which relate directly to the UTP color code. These two standards are called T-568a and T-568B. The T-568A standards states that the blue and orange set of wires should connect to the middle pins and is used more in audio connections. While the T-568B states that the orange and green sets of wires are to connect to pins 1, 2, 3, and 6. T-568A is the preferred standard for wiring however you will find that equipment and cables are still mostly done using the T-568B standards.

The total UTP color code consists of 5 different colors creating several different patterns. The correct color matches are white/green, green, white/orange, blue, white/blue, orange, white/brown, and brown. The white and green wires for the cat 5 color code are used mostly in Recovery Data, orange and white is for Text data, and the blue and brown UTP color code wires are generally unused.
