I've seen Bloom in Alpina Calf but not Box. How they've photographed it on the website is very good capture of what it looks like in the store under their lighting.
I don't think you can go wrong with this color but in looking at what the definition of ballerina pink is online, what you're seeing captured on SM is correct depending on the lighting/angle:
1. Ballet Pink is more of a light "peachy" pink, where Theatrical Pink is a light pink with no additional color undertones
2. Ballerina is a pale, bright, cheerful cerise pink with a rose-pink undertone
