In my experience, making an interview less biased is not about color of skin. It's about comfort and acknowledging how these anxieties creep up. At big companies I've worked at, we coached interviewers to do at least 5 minutes of small talk and resume review, to smile, to always leave time for questions at the end, to show some amount of enthusiasm for the work the interviewee is doing.
It's not about an interview format for a different race but interviews that take into account how being the odd person out may make it harder than it needs to be. In my ideal process, that helps everyone have a better interview.
