You recently applied to a test online for an admission to a secret club and today was the time for testing. You read online that they were looking for people with excellent problem solving skills. You went to the place at the exact time you planned to meet, but no one greeted you. All you saw was a door with a huge sign on - "Entrance test here"...
...You enter in the almost completely dark room with nothing but a small burning candle (looked like it only had a couple of minutes left) and a paper sheet with some text but also a plate with some colored 3D objects on it with different material.
"You have around 5 minutes to look and make sense of what you see before the candle burns out. After 1 hour I want you to give me the full name of a specific person (our top member, actually). If you manage to figure out the name, you've qualified to join our secret club. Good luck."
What name do you give them to qualify to the club?
Note: The puzzle is solvable without the background text/story (which makes this puzzle look more complicated than it is). It's just there for flavor but it has some clues and hopefully it will make sense why I chose those clues once the puzzle is solved.
