Colors evoke emotion. The advertising companies know the colors that evoke those emotions. Here is an example. A headshot of a model, the same headshot, very close to the same expression but the color of her hat and bandana are totally different. I could have had her eye expression more angry. I should have asked her hold old she was or what did she think of her x-husband and just held the shutter down.
Obviously these are set-up or planned photographs. I picked out her as a model including her hat and bandana. What started this was a visit to a used clothing store in Santa Fe. She owned it. I could have spent a week and a bunch of money there making not taking photographs. Model release is really important here.
