Applying palette ideas to a real project

I need to record a short training course for work. The company backdrop is a fairly strong teal. I can choose my clothes, but replacing the background is outside my part of the project. I own a cream shirt, a navy shirt, and a muted red one. I would like to compare those before buying anything. The room, microphone position, and lighting will stay the same throughout the course. I can make these comparison clips before the scheduled recording day, so there is time to adjust my choice without delaying anyone. I found a personal color analysis page while looking for language to describe the differences. I am unsure how much a personal palette tells me about this particular setup. Would you compare short clips with identical camera settings first? I could ask a colleague to assess separation from the backdrop. What should I evaluate separately when judging how my face looks?
