What are colour codes of USB wires?

Most hardware pieces today connected to our CPUs are USB-driven, meaning that they require use of a USB cord or wire. This includes your keyboard, mouse, webcam, memory flash drive, some speakers, the external hard drive, camera or digicam, video cam, and more.

So what is inside it, exactly? USB stands for Universal Serial Bus, and there are four wires inside of it — usually, it's a red, green, white, and black cord. Each of these wires has a corresponding code:

• Red color indicates the positive wire with 5 volts of DC power.
• Black has always been the ground wire in almost all electronic devices.
• White is the data as a "positive" wire, while
• Green is also for the data , but as the negative wire.

Other Colors:

Some USB cords have different wire color combinations, like orange, blue, white, and green. In this case:

• Orange is the positive, with 5 volts of power in the DC (direct current).
• White indicates a ground wire, meaning the negative wire.
• Blue corresponds to the negative data
• Green as the positive data.
