There’s Vantablack, one of the darkest substances known, absorbing up to 99.965% of visible light, and then this new super-white paint capable of keeping surfaces up to 18 degrees Fahrenheit cooler than their ambient surroundings, similar to a refrigerator, but without the energy consumption. This paint could actually replace the need for air conditioning by absorbing nearly no solar energy and sending heat away from the building. Read more for a video and additional information.
In addition to sending heat away from a surface, the paint keeps it away from Earth into deep space where heat travels indefinitely at the speed of light. This means that heat doesn’t get trapped within the atmosphere and contribute to global warming. Technically Earth’s surface would gradually cool with this technology if the paint were applied to various surfaces, like roads, rooftops and cars around the world.

It’s very counterintuitive for a surface in direct sunlight to be cooler than the temperature your local weather station reports for that area, but we’ve shown this to be possible,” said Xiulin Ruan, a Purdue professor of mechanical engineering.
