The cylinder color for R-22 is?

Explanation:
Color coding on refrigerant cylinders helps prevent mistakes by quickly identifying what’s inside. For R-22, the standard industry color is green, so a green cylinder is the quick visual cue that it contains R-22. This helps technicians avoid mixing R-22 with other refrigerants during charging, recovery, or transfer. Always double-check the cylinder label and markings, since colors can vary or be repainted, and the label provides the official refrigerant identification and safety information. Remember that R-22 is an HCFC with ozone depletion potential, so proper handling, recovery, and regulatory compliance are essential.
