Gender Reveal Cake - Pink or Blue???

This was a really fun cake to do. One of our customers asked ask to create a gender reveal cake for Mother's Day. She was finding out the sex of their 3rd baby on Friday and decided it would be a fun Mother's Day surprise for the family to order a cake. She brought the ultrasound results to us so that we could color the cake pink or blue. We created a similar cake for a gender reveal party a few months ago but this one was even more exciting because even the mom didn't know the sex yet. The cake is a 6 inch round with 3 layers of white cake - we tinted the batter of the middle layer.

So was it pink or blue????
