color of injectors

Does anyone have the knowledge of what color to # that injestors are. the stock ones are red, what are they and orange ones off a 4.6 are what?

from:http://fordfuelinjection.com/injectors.html

Fuel injectors are color coded. The color of the injector at the electrical connector determines lbs. per hour. 14 lb/hr are Greay, 19 lb/hr are Orange Yellow, 24 lb/hr are Blue, 30 lb/hr are Red, and 36 lb/hr are Dark Blue.

thanks for the info.
