This conversion exercise from an old terraced house to a shop/office required the preservation of the history of the old red light district of Yokohama. Yasutaka Yoshimura was involved in this project as one of the five architects or artists selected. His poetic intervention was a subtle game of fluorescent light and paint that changed the colour of the room into red for just a few seconds.
Recalling the memory of the red light district with the persistence of a complementary colour was the architect’s concept. Five architects or artists renovated small terraced houses in the red-light district in Yokohama. The house Yasutaka Yoshimura was in charge of is only 10 sq m and the space was divided into two sections, one front space painted in white and the other inner space painted in green. As the spaces were painted with special fluorescent material, the fluorescent lamp magnified the colour of green. After staying in this green room for tens of seconds and retreating to the white room, one can find that the white room had been turned into a red room. This phenomenon is called persistence of complementary colour, which lasts only for few seconds up to tens of seconds. The space recalls the red light that used to shine in this neighbourhood deep in the memory and back into the mind in a flash.
