The design of the Mosa µ [mu] ceramic floor tiles is highly unusual. They are available in four calm colour tones, but they stand out because they respond to the changing light of the environment and subtly go through gradations of colour during the course of the day. This transformation is caused by the ceramic pigments mixed in with the clay and the particular approach of combining different colours. This ensures that the tiles absorb certain light waves and reflect others, thus creating various hues. Their shades change depending on the viewing angle and the distance from which they are observed.
