Why do we call the US Presidential Home the "White House"?

From 1800 to 1814, John Adams (2nd US President) became the first president to inhabit the presidential home of the United States. During this time, the British burned it because the Americans had torched Toronto. The presidential building then became a grey Virginia freestone.

In order to cover up the fire damage, the presidential haven was painted white. However, it was not officially called the White House until Teddy Roosevelt began printing its image on the executive mansion stationery in 1901.
