The next time you need a boost of creativity, whether embarking on a creative project or struggling to solve a problem big or small, try staring at something green. A granny smith, some trees, anything.

That’s what scientists in Germany had test subjects do. Two groups stared at green and white triangles respectively, then completed creativity tasks. The green group was rated as more clever, inventive and better able to solve problems than the white.

Historically, the color green has been associated with life, nature, fertility, growth and hope, so perhaps it’s no surprise that green, in some sense, inspires us. Whether the power of color is based in some innate hardwiring in our brains, or a cultural phenomenon, the reality is that color affects us.
