The video-light installation Civil Twilight - Choreography for 450 nm and 600 nm works with the palette of the night sky colours, a deep indigo-violet-blue and deep orange-red ranges, the shortest and longest wavelengths visible to human eye. It features a cube-like shape in constant movement that plays with the perception of colour and shape. It combines infrathin layers of colour light projected across several surfaces, creating a perceptual continuum between a 2D video image and 3D projection screens, the shape constantly affected by a flux of merging colour fields. Civil Twilight plays on the concept that color does not exist by itself but emerges in an interplay between the light, the surface and the perceving eye.

The installation was first presented within the Looking Glass-House project at the KunstFestSpiele Herrenhausen in Hanover (DE).
