Dark colors tend to absorb light energy. Light colors and white reflect light energy. That's why you might feel warmer wearing a dark-colored jacket than a light-colored one. When light shines on your dark jacket, the jacket fabric absorbs light energy. The absorbed light energy causes electrons in the atoms of the jacket to vibrate. This activity releases heat energy, which makes the jacket—and you—warmer. That's why people tend to wear more dark colors in winter and more light colors in summer.
