R-22 refrigerant is color coded as which color on labeling?

Explanation:
Color coding on refrigerant labeling helps you identify the exact refrigerant at a glance, which is crucial for safe handling and using the right oils and components. For R-22, the label color is light green. This distinct color helps distinguish it from other common refrigerants, reducing the chance of cross-contamination or incorrect servicing. Other colors like red, blue, or yellow appear on labels for different refrigerants or warnings in various schemes, but in this labeling system, light green identifies R-22.
