As part of the highlighting of the pedestrian area of Neuchâtel, general principles were elaborated for the illumination of the symbolic buildings of the center:
> Sobriety in the interventions which means control the lighting intensities, choose wisely the elements to highlight, rather illuminate details than a whole building, etc.
> Harmony in the tones: exclusive use of white light.
For the highlighting of the Townhall, we conceptualised different lasting scenarios for each season: orange tones in autum, golden tones in winter, white and neutral in spring and warm in summer.
For the opening night, a son et lumière show was organised.
