How can I solve this puzzle?
It may help to look at some other puzzles on this floor before doing this one. If you have already, then the one right next to it will help align your thinking in the right direction.
Much like the one to it’s left, you need to do the red one in rows, not columns. Also you should first compare each of the “light sides” (left sides) of the folds in the sculpture and try to figure out which of those three are the light ones and which are the dark ones. Then do the “dark sides” (right sides), and figure out which of those three are the light and which are the dark. Then move on to the next row. Do it row by row, very diligently, and you should get the solution.
