In the episode "Daddy Dre-Care," Ruby tells Rainbow that she at one point lived in New York and sang backup for Bette Midler. In real life, actress Jennifer Lewis was a backup singer for Midler and had a role in her movie "Beaches."
The 23rd episode of the third season, Black-ish: Liberal Arts (2017), functioned as a backdoor pilot for a proposed spin-off of the same title, starring Yara Shahidi as her character, Zoey Johnson, goes to college away from the family. In early May 2017, ABC passed on the pilot, but its cable sister channel Freeform was in negotiations to move the project there. On May 19, 2017, Freeform officially ordered 13 episodes of the spinoff, now under the tentative title College-ish. In August 2017, the series changed its title to Grown-ish. The series's pilot premiered on January 3, 2018.
Since the second-season premiere, the show has received critical acclaim, receiving many awards and nominations including a Golden Globe Award for Best Actress for Tracee Ellis Ross, Emmy and Golden Globe nominations for Outstanding Comedy Series, and a TCA Award for Outstanding Achievement in Comedy.
Rainbow's zodiac sign is Virgo. In a flashback scene in the episode "Being Bow Racial," we see young Rainbow confused as to whether she should select the white or black ethnicity box on her form. On the form, it shows her date of birth: September 6.
