Ambient light plays a central role in the Annie-Pelletier pool. The project evokes a prism breaking light up into its multi-coloured spectral colours. Coloured panels define the different areas through the use of distinctive colour palettes: blue for the main pool, yellow for the children’s recreational pool and green for the locker room area. And although they are located at different ends of the building, each luminous pool can be seen from the other through the many windowed openings separating them. White has been used generously in the project and paired with the space’s neutral finishes, serves as a canvas on which the elements of colour are expressed. But water is the essence of the project. It reflects and flickers, transforming the space according to the daily or seasonal changes in light.
