Scientists at Oregon State University have discovered new "colors" that reflects heat.

Chemistry professor Mas Subramanian first discovered a blue pigment three years ago.

It was beautiful and vibrant, and unlike most other pigments, non-toxic.

But that wasn't the only thing that made the blue so “green.”

Subramanian recently learned that the dark blue pigment also had unusual chemical characteristics that reflected heat.

If used on roof-tops or building walls the pigment could actually keep structures naturally cooler, dramatically increasing their energy efficiency.

“Compared to the blues we know today, like cobalt blue for example, these can reflect at least 40 more than what is being done today,” explained Subramanian.

The professor has also developed other "cool colors" including greens, browns, even orange.

Several companies are now testing the paints for potential commercial use.
