NBC NATIONAL NEWS — 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 â€œgreen.â€
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.
â€œCompared to the blues we know today, like cobalt blue for example, these can reflect at least 40 more than what is being done today,â€ 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.
