Hello! Thank you for playing and for your comment!
I will send you three hints for this puzzle, each one more obvious than the last:
Hint 1: On the shelf of the cabinet, there is a photo from when we first moved into the apartment. Something is strange in the photo.
Hint 2: Two items in the photo look very strange. But where are they located? Between two doors of different colors.
Hint 3: There are two cabinets between the blue and purple doors in the photo. You need to place them in the same position as they are in the photo.
