Polystyrene Wallpaper Need Colour Scheme Tips For My Dark Hallway?

Need colour scheme tips for my dark hallway? - polystyrene wallpaper

I robbed a fairly long corridor and close only by his terrible ceiling tiles, polystyrene and wood chips, yellow paper. Now they want to put some wood floors and paint to create the illusion of a bright, welcoming environment. Very little natural light, although a little clearer on the other side, as the light shines through a glass door panels for my living room to the west. All ideas very welcome.
