Color of runner duckling? PICS

[jdywntr]

I have 11 runner ducklings ~4.5 weeks old. Moms were either black, blue or fawn & white. Dads were either black, chocolate or fawn & white. What color would this one (in the center of first pic and left in second) be called? It looks like chocolate milk. I'm thinking F&W mom and chocolate dad.

Also, the white (left in first right in second) has speckles of (I think) blue. Is this called a particular color?

Thanks.
