You will gain rainbow keys by either finding them in stages or by solving light beam puzzles. However you obtain them, having them is a requirement for Perfect Porkchop 
. There are a few gold keys to help progress further through the dungeon - you will obtain these via story progression, and these keys also count towards the trophy.
There is a light beam puzzle that spans the entire left/west side of the palace. To save yourself a headache and backtracking, take care of the puzzle steps whenever you come across them. It's not a difficult puzzle; it's fairly obvious where you need to aim the light beam. Generally-speaking, you want to keep the beam going up/north. Near the Stairway entrance point, the light puzzle will end up going left/west to the final part, which is nar the Balcony entrance point.
Reddit user linlaowee (with assistance from cryptoxima) has put together a map of the Palace of Light, complete with treasure and ore locations, to help you navigate. Note that this is the same map twice, with the right map showing the lower levels that are blocked by the upper levels.
