Portal Transition Lighting Glitch
Okay, this is weird. A glitch, probably. If you go through some portals to either the light or dark worlds, sometimes, the light reflected off of Samus's suit during the transition will be misplaced.
Like, white light will be reflected off of some side of her suit, yet that side of the suit may be facing the dark end of the portal transition. This does not apply for all portals.
The first two portals in the game properly place the light reflections.
