Tag your most inspiring and colorful Twitter and Instagram posts with #SWCOLORLOVE or upload a photo. Scientists have been developing reflective paints for decades, but todayscommercial products still remain at or above the surrounding temperature. Editors Note (7/16/21): A version of this article with the title Cool Color was adapted for inclusion in the August 2021 issue of Scientific American. White paint absorbs up to 40% of the spectrum in the same way that any other color is, so neutral white paints reflect the most light.

This is an accurate view of most reflective paints in the world market (Kondo, 2006). "We looked at various commercial products, basically anything that's white," said mechanical engineer Xiangyu Li of the Massachusetts Institute of Technology, formerly at Purdue. The benefits of heat reflective paint in lowering surface temperature are relatively small for the cooler light coloured paints. Paint additives consisting of crushed glass powder improve its reflection as they are used to achieve the same effect as crushed glass paint. Our paint does not use any power but, more importantly, it sends the heat to space.

Xiulin Ruan, a Purdue mechanical engineering professor, added: If you were to use this paint to cover a roof area of about 1,000 square feet (93 sq m), we estimate that you could get a cooling power of 10 kilowatts. Because of the limitations of the materials, the barium sulfate paint probably can't get much more reflective, but what the team has achieved could actually change the world for the better. And Yang notes that any new product like this will need to stand up to the real world, where grime coats surfaces over time.

If you can efficiently reflect IR in that range there is less absorbance causing the surface to heat up. One way buildings can earn that credit is to use materials or devices with an initial solar reflectance of 33 percent at installation or 28 percent over three years, Thompson says.
