Typical RCA cables will have two or three color coded connectors. RCA audio cables have two connectors: red (right stereo) and white or black for left stereo. An additional third connector on an RCA cable will be yellow for composite video.
Here is a typical color coding of RCA connectors:
| Composite analog video | Composite | Yellow |
