German ad agency Thjnk and production studio I Made This teamed up to create a unique RGB Billboard that revealed different messages depending on the colored lights.
The billboard featured three different messages in three different colors. Cyan, magenta and yellow. At night, the billboard was lit up by red, green and blue (RGB) light bulbs, which made the different messages visible depending on the shining light bulb.
The red showed the cyan text. The green made the magenta text visible. And the blue light revealed the yellow text. With this simple visual trick, the billboard made the most of its limited space and embodied Ikea’s space-saving message.
How the RGB trick works
The idea leans on a simple perception hack. You print multiple messages in different ink colors, then you control which one becomes dominant by changing the light color that hits the surface.
By switching between red, green, and blue lighting, the billboard effectively “filters” what you see. One physical surface. Multiple readable layers. No moving parts required.
Why this is a very IKEA way to communicate
IKEA’s promise often comes down to doing more with less space. This billboard does the same thing. It demonstrates the benefit while delivering the message. The medium becomes the proof.
It is also efficient. One placement delivers three messages, but it still feels coherent because the mechanism is consistent and easy to understand once you see it happen.
What to borrow for your next OOH idea
- Make the constraint the concept. Limited space becomes the creative engine.
- Use a mechanism people can explain. “Different lights reveal different messages” travels fast.
- Build a repeatable reveal. The change over time, or over conditions like day and night, creates a reason to look twice.
