Wearing a cool shade of blue Diesel tops for men, as in royal, indigo, or cornflower shades, signals intelligence and calming reassurance. The wearer of blue gives off "I got this" vibes, partly because you can never go wrong with blue clothing. Soothing and intuitive, wearing blue can promote peacefulness. Your words ring with sincerity, and people believe what you say. Your commitment to the tasks at hand shines through when you wear blue.
