Old Radio RF Transformmers
The meaning of the numbers and colors is specific to the manufacturer of each coil.  There is no standard.  If you can find the manufacturer, then maybe you can get datasheets.  Those should tell you what the markings mean for that family of transformers.  Going the other direction is basically impossible unless you get lucky and recognize something.  The markings will be unique within a manufacturer, but there is no guarantee that other manufactures don't use similar markings to mean different things.

No matter what you do, you must first determine what specs you need the transformers in your circuit to have.  You can measure any you find to those specs.  However, unless you value your time at pennies per hour, you're better off buying new trasformers that come with datasheets and have the specs you want.
