CTC (ColourToColour) is a new dual-brand retail concept developed for Gebr. Coster (The Netherlands). The shop is conceived as a basic box. Splitting it up into two parts creates individual store space for two selected fashion brands G-star RAW and adidas Originals. The brand spaces are linked and divided by the CTC zone. Utterly prominent in this zone, from floor over walls to ceiling, a single colour amplifies all shapes and objects, and interconnects everything in its path.
