They could be pastels. The adults are darker than the babies. The pastel mutation creates a lighter boa that is nearly fleckless. It is often used to "clean up" other colors and patterns. But the adults are going to look more normal than the babies would. Neonates will be very clean and pinkish (almost like a hypo) but they will tend to be more grey and have some flecking as adults.
The female does seem to have more black on her tail than one would normally see on a pastel, but she still could be pastel. It will be interesting to see what the babies look like! They are both very handsome boas!! Good pickups for $150!
Love your racks! I'd give my eye teeth to find a pair of 4' pvc cages for $175!!!![]()
