What color is used to designate a 20-gauge IV catheter?

Explanation:
Color coding of peripheral IV catheters helps clinicians identify gauge size at a glance. The pink designation corresponds to a 20-gauge catheter, making it easy to choose the right size for routine IV infusions without measuring. A 20G line is a common, versatile choice for adults because it balances adequate flow with vein safety. In this color system, blue usually marks a 22-gauge (smaller), and green marks an 18-gauge (larger); white is not part of the standard color scheme.
