The IKEA RGB Billboard

Whether you’re working in interior design or advertising, having limited space demands clever solutions. Despite the small surface area of our billboard, we were able to come up with a striking and distinctive design that packs information together stylishly. Using three lines, three colours and three light bulbs, we made a billboard that is capable of showing a series of different phrases. When it’s illuminated by green light, only the text printed in magenta is readable. Blue-purple light makes yellow visible. Red light reveals blue. We effectively turned a nine m² surface area into a 27 m² one.
