“I had the best time at the EW party Friday night, getting hyped for the Emmy’s, our upcoming Grey’s season premiere this Thursday, and celebrating artists who have created visionary, groundbreaking television for us to enjoy this fall,” she wrote on the photo sharing network.

“Saturday morning, I searched the internet for my carpet photos so I could post them here and give credit to my glam team who straight KILLT it, but I could find none,” she continued. “Finally, with a sinking feeling, I searched for the name of my castmate, Jerrika Hinton, who did not even attend the event. Lo and behold, there I was!!”

“[T]his isn’t the first time this has happened,” she explained. “Now Jerrika is a beautiful lady, inside and out, with talent for days. I would be flattered to be mistaken for her, if it didn’t seem like the all-too-frequent occurrence of this [mistake’ indicated the careless conflation of two black actresses with curly hair on the same tv show.

“I wonder, does this happen when there are two blonde women in the same cast? When there are two dark-haired white dudes with blue eyes? Maybe it does. But I’ll tell you what— to constantly wonder whether I’m facing a micro-aggression I should call someone out on, or a harmless mistake I should let slide, is a real energy drain.”

“Check your unconscious biases today. We all have them. Managing them takes discipline, vigilance, and self-awareness, and you can practice it anytime. Why not do it today? And in the words of my castmate, I simply ask the folks who are in the business of identifying distinct and unique human beings to Do Better. That is all. Thanks.”
