A new study shows that ancient humans painted their homes with natural colors to brighten up their dwellings and enhance important buildings.
Excavations at a Stone Age settlement on the Orkney Island in northern Scotland revealed that man's ancestors made paint by using earthy colors like oranges, yellows and reddish-browns pigments from ground-up minerals and mixing them with animal fat and eggs.
Researchers found a number of painted and decorated stones which they say belonged to buildings constructed by locals in about 3,000 BCE.
Archeologists say the stones might have been used in entranceways or areas of the building, which had particular significance. They were also used to mark important buildings in the area.
“We have found seven stones in this ritual center,” The Daily Mail quoted Nick Card of the Orkney Research Centre for Archaeology as saying.
“Some of them were covered in paint and others appear to have had designs such as chevrons and zigzags painted on," he added.
"Paint pots have been found at various other sites before but we assumed this was for personal adornment. But we now know they used it to paint their walls."
