This is why you need to memorize your lines and look directly into the camera. Don't wear red, black or white. Be careful what you wear on-camera. Red sometimes looks smeary on television. Black and white offer too much contrast.
Tight patterns can cause signal noise on-screen.
The best colors for video are greens and blues. If you want to appear as if you're wearing a black suit and a white shirt or blouse, you can wear a dark blue suit and a light blue shirt or blouse. The magic of TV will change your outfit to black and white. Everyone will be happy. If possible, bring a number of clothing options to a shoot, blazers, sweaters, shirts, blouses, shoes, etc.
