We don't use color coding in my center yet, but, historically speaking, yes, red is next day, blue is 2nd day, and orange is 3 day select. They used to have shippers put color coded tape on packages indicating service level (now discontinued), and old hand written labels (which can still be used) are color coded as written above. Ground may have brown, but I can't remember for sure off hand. I like the color coding because I've had problems with bulk shippers mixing next day in their ground. As careful as I try to be, I'd still miss one from time to time, which is bad news...Oh, I get it. However, it does seem that around here Next Day Airs usually go on the "Red" belt, and 2nd Day Airs usually go on the "Blue" belt. Is this a common practice?
