Exactly why I said in your other thread that I think he's a mix. I believe he's most likely half N half. He does show strong BCC influence. The 13 saddles, the head shape, the color and drastic color changes. But he is also lacking some key characteristics. Eyelash markings, connected saddles (the line along the sides which usually appears on the ones who lack major peaks), any peaks.

While my own Suri lacks many peaks, most of her peaks connected to form partial stripes. Perfect peaked saddles are not always THE indicator for BCC but don't get worked up over it.

So what if it's a Colombian or a mix. Honestly if the person it originally came from said Colombian that's what it is. Wether it has other blood mixed in there or not.

If you ever do decide to breed boas, unfortunately you won't be able to market it's offspring as anything other than BCI but that doesn't mean you can't mix it with some awesome BCI genes. Like albino, motley, etc..

Like another poster said, give it time. Age, color, size, may all tell you eventually if it is more likely to have BCC in there.

The housing differences are not drastic enough to matter. Mine is kept in a Boaphile cage stack with other snake species in the stack and she favors the hot side. saying they like it cooler doesn't apply to her.
