Colorful

This is an interesting fact you might not know about the Colosseum may surprise you, but most buildings and temples are repainted at that time. Travertine, limestone is used to make colosseum, is a porous rock. They used a technique called Scriptura, which basically meant that people covered a thin layer of mortar and marble dust to prevent rocks from worsening. Basically, this will give the original white pale or beige white. For the rest of the building, they painted the arches and all the statues to make the entire complex more vivid and more colorful.

During the restoration of the Colosseum in 2013, the restorers discovered the ancient colorful mural in a closed tunnel leading to civilian seats. After decades of not being touched, the restorers have brushed a layer of lime and dirt, revealing bright paintings with red, blue, green, and vivid white. They also found historic graffiti paintings left by the audience, such as crowns and palm trees. This led historians to believe that the tunnels inside Colosseum could be filled with paintings and colors during its original period.
