She is survived by her sister, two other siblings, and her son Michael.
Shaun Chang, a movie and TV blogger quoted by The Hollywood Reporter, remarked on Colbert’s role: “As the only African-American character who appeared more than once, Dora Mae never had a storyline because Dallas focused primarily on the Ewing family.
However, she played her part with elegance and intelligence.
The show treated her with respect, making her an important part of the community feel of the series.”
Dallas, which premiered in 1978, was canceled in 1991 due to high production costs.
