Women wanting to attract men should wear red, specifically a bright orangey-red. That color sets off a chemical chain of events in a man's body that compels him to respond positively. Seeing red causes the brain to signal the body to secrete epinephrine, a hormone that causes the heart to beat faster and the body temperature to rise. Mom's lips are red. Mom's nipples are red.
Infants love red, and most men never get over it.
If red gets us excited, it's pink that calms us down. Some years ago, researchers tried painting jail cells pink to see if that defused prisoners' aggression. They used a bright shade called Baker Miller pink, commonly known as Pepto-Bismol pink. In tests at a Seattle jail, prisoners not only stayed calm in the pink cell, the effects lingered at least 30 minutes after being removed from the cell. You can use this to your advantage, Olsen says.
