I'm not sure what this triangle is, but I've been looking for a faint white outline on the border of the tiles, I've got a solution for myself after several runs till I cleared ex4.

Starting at the least obvious quadrant where non rose players should be made it easier to recognize the faint white outlines that border the tiles.

It is the only part that I needed quicker response to react.

The only issue with the typical method I use would be the white borders make the tiles on the side look the same if I glanced at it wrongly for how everything seemed to be bordered when there's an odd one out.

For Zelenia, the red "gloom" tiles also have a second triangle drawn within them, but it's arguably a bit too subtle and not distinct enough from the rose-motif pattern on the floor.
