Greenhouse (Bunker)
Walk over the mountain path, cross the stream then head to the coast to find this colourful area. You'll need to head down the cliffside path to reach the entrance.
Hint: The initial panels are just standard colour block separation.
Open the door to access the next panels.
Hint: You need to filter out some of the colours.
Looking through the yellow filter will reveal the solution.
Hint: Try a different filter.
The next panel requires a blue filter to reveal the solution.
Hint: Try a combo.
The third panel needs a green filter to find the solution, so look through both filters.
Hint: Shed some light on the problem.
The switch in the corner will open up the current area, to reveal the solution in the sunlight.
Conversely, the next solution requires the magenta light inside, so close the area up again. Head into the new area then down to the ground floor to locate an elevator.
Hint: The solution depends on the lighting conditions.
Work your way up the floors, but at this point you'll discover the cable for the current level is broken.
Hint: Think about the conditions on the floor above.
Looking up, you'll see the next floor has green lighting. Use the rules determined by the yellow/blue/green filters in the earlier area to work out what the green solution should be.
Hop out of the lift on the way through the green floor to find a recording in the corner of the grow room.
Back on the surface, the true colours are revealed for the last solution.
Swipe the lock to activate the laser, unlocking the Bunker trophy. Use the previous solution to return the lift to ground level.
