A true red tail is a BCC and all other "red tails" are BCI.
The biggest difference is a B. C. Imperator (BCI) is commonly refered to as a "red tail," but their tail is typically more orange/brown w/black. They will have some red hues and pinks through out their body, but not anything outwardly bright typically.
B. C. Constrictors (BCC) are "true" redtails. They are beautiful animals, with much bolder patterns and brighter coloring than a BCI typically, especially in the tail.
There are also size differences, and some will claim temperment differences.
Truth of it all is they're all magnificent animals, it just comes down to preference.
The "Columbians" you've found are probably BCI/BCC hybrids at best, and are in fact not "true" redtails. BCIs are the most common boa in the pet trade, often called "Columbians" out of some sort of habit I guess, but they can be one of two or three locales. However, they are what most of us recognize as a "Redtail Boa."
