The blue hallway stretches long and narrow, bathed in a calming yet mysterious hue. Cool-toned walls shimmer under dim overhead lights, casting soft shadows that dance along the polished floor. A faint scent of aged wood and fresh paint lingers in the air. The deep blue color shifts with the light, appearing almost navy in the corners yet electric near the sconces lining the walls. At the far end, a single door stands slightly ajar, its dark frame contrasting starkly against the blue expanse. Footsteps echo as if swallowed by the walls, adding to the hallway’s eerie tranquility.
