What is the color code for audio?

The color code for audio ports is standardized to make it easier to identify the correct ports for different devices. Here’s a breakdown of the most common color codes used for audio connections:

Standard Audio Port Color Codes:

1. Green – Audio Out (Speakers/Headphones)
   This is the most common port used for connecting speakers or headphones. It carries the audio signal from your PC to external devices.

2. Pink – Microphone (Audio Input)
   The pink port is typically used for connecting a microphone to your PC. It handles audio input from external microphones.

3. Blue – Line-In (Audio Input)
   The blue port is used for line-in devices, such as external audio sources (e.g., a musical instrument, another computer, or audio mixer).

4. Black – Rear Speakers (Surround Sound Setup)
   The black port is used for the rear speakers in a surround sound system (e.g., 5.1 or 7.1 setups).

5. Orange – Center/Subwoofer (Surround Sound Setup)
   The orange port is used for the center speaker or subwoofer in a surround sound configuration.

6. Gray – Side Speakers (Surround Sound Setup)
   The gray port is sometimes used for side speakers in advanced surround sound setups.

7. S/PDIF (Optical) – Digital Audio (Optical Connection)
   If your device supports digital audio, it might use an S/PDIF connection (often a Toslink optical cable) for higher-quality sound. This is typically not color-coded, but it's another method for connecting audio devices.

Summary:

• Green: Audio output (speakers/headphones)
• Pink: Microphone input
• Blue: Line-in audio input
• Black: Rear speakers (surround sound)
• Orange: Center or subwoofer (surround sound)
• Gray: Side speakers (advanced surround setups)
• S/PDIF: Digital audio input/output (optical)

These color codes ensure easy and correct connections for your audio devices, making it simple to set up your speakers, headphones, or surround sound systems.
