She may also be a pastel - which isn't a genetic morph but rather a color phase. Pastels often carry a bit more pink highlighting. I might've even said hypo, but she's got a bit too much flecking and grey tones to be a hypo. Pastels are often used to "clean up" the pattern and/or color in other morphs.
Boas also can be a chameleon of sorts and they have "dark" and "light" phases of their normal coloring. They will sometimes even appear to blush.![]()
