What should be the phenotypic ratio of a test cross between a trihybrid and a homozygous recessive parent?

What is the phenotypic ratio of a test cross in the $F_1$ generation of a dihybrid cross?

In humans, brown eyes $(B)$ are dominant over blue $(b)$ and dark hair $(D)$ are dominant over red hair $(d)$. A man with brown eyes and red hair marries a woman with blue eyes and dark hair. They have two children; one resembles the man (brown eyes, red hair), and the other resembles the woman (blue eyes, dark hair). What are the genotypes of the man and the woman?
