Can colour replace a screen?

Lentos in Linz is a useful boundary case: a programmable, colour-changing architectural skin, not a video wall.

Weber & Hofer's museum opened in 2003. Its glass facade reflects the riverfront by day and becomes a luminous surface after dusk. Historical engineering descriptions document control of colour and brightness, not film playback.

My planning takeaway: a building can mark the skyline without becoming a giant screen. But visibility is not proof of tourism or spending uplift. Current lighting hours, energy use and uninterrupted year-round operation were not verified.
