A spectrum is a set of colored bands produced when a light beam passes through a refractive medium. it symbolizes versatility, variability, and hidden potential. The project uses all possible interpretations of this concept: from the literal — working with natural and artificial light, to the metaphorical — transformation of space from one state to another.
A "double shell" is created inside the bar, covering the stone walls like decorations. the whole interior is a new space contrasting with the building. This has already been laid down during construction, it needs to be developed and strengthened. The space expands and transforms due to mirrors, the frequent step of structures and the spread of natural light on the spectrum.
