Meaning of オレンジ in オレンジは右側です


I couldn't find the answer to this.

Sometimes when I'm on the subway in Japan when getting close to the next stop
in some trains it can be heard **オレンジは右側です** , not sure if it's **オレンジ**
though. Meaning the exit is on the right or left side, any clue if it's saying
**オレンジ** or anything else? If **オレンジ** is being said, why orange?




They are probably saying:

> お出口{でぐち}は右側です

Meaning, of course, the exit is on the right.
