The question
How is a refillable refrigerant recovery cylinder usually identified by color?
- The color of the refrigerant it holds
- Solid green
- Red body with a white top
- Gray body with a yellow topCorrect answer
Why “Gray body with a yellow top” is correct
Recovery cylinders are commonly painted with a gray body and a yellow top (shoulder). They must be DOT-approved for refilling. Disposable cylinders of new refrigerant are color-coded by refrigerant type instead.

Why the other answers are wrong
- The color of the refrigerant it holds — Refrigerant-specific colors are used on new-refrigerant cylinders, not recovery cylinders.
- Solid green — Solid green is not the recovery cylinder color code.
- Red body with a white top — Red with a white top is not the recovery cylinder color code.
