Two years ago as a part of a promotional strategy, Volvo released the LifePaint, a water-based, non-toxic reflective paint that seemed invisible in daylight, but the minute it gets dark, the paint catches stray lights to reflect them, thus illuminating the object. Albedo, a Swiss-American company decided to turn campaign into life-saving product with their . The invisible paint comes in permanent, semi-permanent, and non-permanent variants, and can be used on everything from clothing to walls, to (stuff like horses or reindeer that sadly become roadkill because they go unnoticed in the dark). They’re non-lethal, but you wouldn’t want to swallow the paint. Aside from its life-saving properties, the invisible spray could even be used in a number of creative ways, creating graffiti that only shows when someone shines a light on it, or unconventional flash-photography where scenarios completely change under the influence of the reflective paint. The Semi-permanent paint washes off clothes easily, while the non-permanent paint can come off with a damp cloth. Designer: Albedo 100
