what color is your cousin?

A few weeks ago my sister and I were invited to our cousin's baby shower, along with our own bundles of joy (her three -- 5- and 3-year-old boys and 1-year-old girl -- and my one mook).

The boys had just finished a soccer game and were hot and tired and wanted to go home, so Beau, the 5-year-old, asked his mom where they were going. She told him they were going to a baby party for our cousin. Beau has lots of cousins on his dad's side and one cousin on his mom's side -- our mook. So his question made sense to those of us who have seen the family:

"What color is she?"

This led to a long exchange about what color everybody was, and how they're all part of our family and we love them.
What color is Beau? White.
What color is Noah? White.
What color is Paige? White.
What color is Emma? Brown!
