“Junin toiro (many men, many minds)” (TOIRO)is The rent space which a country manages In this facility that is named after “junin toiro”, I imagined the personality of each perosn as “colors”. When you walk across the white space, your shadow will be colored by the principle of “(*)additive mixture”. This allows the space to become a place where people are able to see the “color” they primarily possess, but not seen usually. Moreover, when people gather and the community becomes larger, a lot of shadows come together, gradually putting “colors” in a space where there was nothing. And in each room, I expressed the layer of the “colors” by materials, which means placing the floor materials in layers and those layers of floors change colors, creating a various sized areas within the space. *additive mixture (color shadow) Additive mixture is a mixture that the brightness gained from the colors you mixed is the same as the sum of the original colors. The more colors you mix, the brighter it becomes. If you mix “light’s three primary colors”, red (R), blue (B) and green (G) in even amount, it will become white.
