Jason,
The coloration of your boa in your photographs as the shown on my computer are not even a hint of pink in them. The lower photograph show a more basic orange coloration whereas the closeup on the bark shows shows a dorsal coloration that is orangish-brown. Both dorsal colors are typical for a boa of that size (9" - 10" stretched length) that is around 1 to 2 years of age.
