Whitest of white paint to get invented by the engineers of Prude University Indiana , who made research on a white paint which really reflects back 95.5%o of the sunlight and it's heat back to space . That means if this used in painting buildings then you won't even need air conditioner to cool down the room temperature as this paint will ultimately keep your room inside cool and may be you get affected by the rest 4.5% of the absorbed heat . As of till now no paint has did this extreme yet the highest was the paint which reflects around 90% and that was the highest one and also one of the costliest too. This paint keeps the surface 10 degree celius below the ambient temperature at night and 1.7 degree celius below ambient temperature at noon that's a lot of cool down for any room inside and that too the paint is not going to be that costly may be it's going to be cheaper than the other paints in market now . This isn't over yet the paint is also anti moisture that is waterproof in rainy and also dust proof too . The researchers took almost 6 years to make this possible by mixing 5 different substance like sea shells and rocks  (not revealed yet sorry !) the primary component of the paint is normal use of calcium carbonate .

"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 professor of mechanical engineering at Purdue.

The as yet-unnamed paint is essentially the opposite of vatanbalck that is the blackest paint of all time which absorbs 99.6 percent of sunlight .
