This photographer turns big cities into psychedelic worlds using Photoshop

18-year-old German architecture photographer and student Paul Eis takes photos of large buildings for a living. But one day, as he sat in front of his computer looking at some of the photos he had taken that day, he was suddenly hit with inspiration.

"I started to think how the buildings would look if they were colorful," Eis told Business Insider.

Eis decided to use Photoshop to add bright colors to the buildings and really make them pop. "Architecture should not only be understood as something useful, but also as artwork," Eis said. "But that is very difficult when you just see gray buildings. Highlighting the structure with bright colors and showing them isolated from their environment helps to show the viewer how unique these buildings are."

Below, see what these white buildings would look like if they were decked out in bright colors.
