The Dawn Of Standardization
As the use of AUX INs became more widespread, there was a growing need for standardization. The Audio Engineering Society (AES) and the International Electrotechnical Commission (IEC) worked together to establish a set of standards for audio connectors.
These standards, known as IEC 268-2 and IEC 268-3, established guidelines for the design and implementation of audio connectors, including the AUX IN. These standards have since been adopted by manufacturers worldwide, resulting in greater uniformity and compatibility across different devices.
The Color Of AUX IN
Now that we’ve explored the history of the AUX IN, let’s get back to the original question: what color is AUX IN?
Unfortunately, there is no single answer to this question. The color of an AUX IN can vary depending on the device, manufacturer, and even the country of origin.
However, according to the standard IEC 268-3, the primary color for an AUX IN is yellow. This is due to historical reasons, as yellow was a readily available and highly visible color that could be easily associated with the AUX IN.
In practice, however, the color of an AUX IN may differ. Some devices may use a green or blue connector to differentiate the AUX IN from other ports. In some cases, the AUX IN may not be color-coded at all, requiring the user to consult the device’s documentation or markings.
Color Variations
Here are some common color variations for AUX IN connectors:
- Yellow: The standard color for AUX IN, as per IEC 268-3
- Green: Used by some manufacturers to differentiate the AUX IN from other ports
- Blue: Used by some devices, particularly those with multiple inputs
- Black: Used in some older or simpler devices where color-coding is not necessary
- Silver or White: Used in some high-end or premium devices to distinguish the AUX IN from other ports
Weird and Wonderful Variations
In addition to these common color variations, there are some device-specific and unusual implementations worth mentioning. These include:
- Multi-color connectors: Some devices use a single connector with multiple colors to indicate different functions or modes.
- LED-lit connectors: Some modern devices use LED-lit connectors to indicate connectivity or activity on the AUX IN.
It’s essential to note that these variations are relatively rare and usually occur in specialized or high-end devices.
Types Of AUX IN Connectors
In addition to the standard IEC 268-3, there are several other types of connectors used for AUX INs. These include:
- 1/8 inch (3.5 mm) Mini-Jack
- RCA
- DIN
- 1/4 inch (6.3 mm) Jack
Each type of connector has its own unique advantages and disadvantages, and some are more suited to specific applications than others.
Common Applications
AUX INs are used in a wide range of devices, including:
- Audio amplifiers and receivers
- Portable music players
- Computers and laptops
- Mobile phones
- Gaming consoles
- Automobile audio systems
In each of these applications, the AUX IN serves a vital function: to allow the user to connect external devices and expand their audio capabilities.

What Does AUX IN Stand For?
AUX IN is an abbreviation for Auxiliary Input. It is a type of input that allows users to connect external audio sources, such as portable music players or smartphones, to a device, such as a car stereo or home audio system, and play audio through it.
In simple terms, AUX IN is a way to connect two devices, usually with the help of a cable, and allow audio to be played from one device through the other device’s speakers or system.
What Is The Original Intent Of The AUX IN Color Code?
The original intent of the AUX IN color code is to create a standardized color scheme for audio inputs and outputs. This would make it easier for users to identify the correct input and output ports on their devices.
The color code is intended to be universal and consistent across all devices and brands. However, as technology has evolved and devices have become more diverse, the color code has become less standardized and more arbitrary.
Why Is There Confusion About The AUX IN Color?
There is confusion about the AUX IN color because different manufacturers and devices use different colors for their AUX IN ports. While some devices use white or red and white, others use a different color altogether.
