Question About Level 2 Pyramids (SPOILERS)

[UnnaturalHabitat]

In the Level 2 pyramids, there are windows that look out into areas with blank Pink Cubes embedded into the walls. Can anyone who's solved them please give me some hints on how to figure them out? I think it might have something to do with the colors of the walls they're embedded in, but I'm not sure.

It does have to do with the color of the walls.
You may want to come back to them after other puzzles.

Thank you for the tip. If my instinct is right, it seems that the blank pink cubes on the outside relate to the pink cubes with clues in different colored pyramids (e.g. the pink cubes in the brown pyramid are in a mint wall, and the pink cubes in the mint pyramid's answers were emotions, so the blank ones in brown are also emotions. Incidentally, could I ask for a hint on the entry puzzle to the Purple Pyramid, and perhaps where to look to access the yellow chamber in the hall of colored chambers (that one and mint are the only ones I have left)
