Why did Rosa Parks become the face of the boycott as opposed to Claudette Colvin?

I believe because Claudette did not have what was considered "Good hair" and she was not fair skinned. She was a teen and pregnant and she was not appealing to protesters

Answer:On December 1, 1955, Parks was arrested for refusing a bus driver's order to give up her seat, just as Colvin had been. But the direction the two cases took soon diverged: The Monday after Parks' arrest, the black community began to boycott Montgomery buses.
