Dr. Anna has brown skin and hair. Her black hair is tied into two twin plait braid pigtails along with two pink hair elastics, and is most likely South Asian as you really know.
According to Angela C. Santomero, the creator of the show, Doctor Anna is based on her childhood doctor, Dr. Sidhu, as the two resemble each other in appearance. She says that Dr. Sidhu even had a fish tank in the waiting room in the same way that Doctor Anna does. 
In Mister Rogers' Neighborhood, Doctor Bill Platypus had a daughter named Ana Platypus and Margaret Witch's crystal ball showed her becoming a children's doctor in the future. Her name was once spelled ANNA on her Someplace Else nametake.
In The Daniel Tiger Movie: Won't You Be Our Neighbor? a character named Doctor Platypus was introduced as the mother of Daniel's new classmate Jodi Platypus, with the family becoming the Tiger family's next door neighbor.
