The problem with color codes is that you need a lookup
table to decode them. And you need to mark the vendor
so that you know whose table to use. When I see a color
coded core I think Micrometals, not Fair Rite.
I prefer to mark cores with white-out pens so I
can write whatever text I want such as F/R 33, etc.
It is also possible to wrap the core with white
electrical tape and write on it with a sharpie or ball
point pen. A 3rd alternate is to use a P-touch labeller.
