The light in the house changes with the seasons. The reason for this sudden luminescence in this dark hallway in Fall and Winter is probably because the sun is lower in the sky for us during these seasons. This causes the sun rays to come streaming in through the third floor window into the hallway. More information about the sun and its position during the Winter can be found here.
We painted the railings recently in Benjamin Moore paint in Onyx and chose a high gloss finish which is perfect in high traffic areas. The print is from this shop on etsy.
