What can be called a good public space design? For a long time, the judgment standard of public space design is that how many people can be gathered in a space. But now this standard is doubted gradually. Designers are more concerned about the influence of the design to the perception of human. Therefore, the appeal for building interactive public space appears.
The quick development of this age not only brings the convenience but also the high wall among the people invisibly. In a kind of self-mockery, some people would like to call themselves “wage slave”, “homebody” or “empty-nest youth”. In the society with low trust and low connection, the interaction among people is not active any more. Aiming at such current social situation, Antao AHA Group innovates boldly, trying to add color to city public space and getting rid of loneliness. As a result, the rainbow channel born.

Rainbow channel is a public beneficial space project designed by Antao AHA Group. It is a point in “Community Awareness Action”, which is sponsored by Jindi Huadong, supported by Nanxiang government and built by many forces. The channel is between Shanghai Nanxiang subway station and Jindi Green World, Green residence. As the only way home, it was once widely criticized: “It is dark, making people afraid.” “It is cold and cheerless in the evening.” “It has no light.” – After the group surveyed and interviewed the passers-by, they find this path is dark in the evening, making people afraid. This survey let designers get the point: the lack of “light and warmth”. Therefore, they have the design idea of “the most beautiful way home”.

From the view of designers: the light is what the way space in Green World wants most. How to design the light is the initial point of making channel device. I hope this light is beautiful, pure and full of energy, just like the gorgeous colors painted by the children. I want to design a happy way home and also hope that it is the start point of a new journey every day for the residents in Green World. Rainbow is a dream like beautiful scenery in the atmosphere. I hope the rainbow can light the way home, and hope purely that the people walk by can have a good emotion.

彩虹通道是感性的设计，但却基于理性研究的基础之上。无独有偶，国外同样有人尝试用彩虹色装点人们生活的公共空间。从2012年开始，温哥华的Davie和Bute街道就把4条马路口的斑马线画成了彩虹颜色，这一实验被证明非常成功。“Happy City的创始人Charles Montgomery和加拿大滑铁卢大学就是否彩虹斑马线真的能改变人的感官进行了实验，他们给超过100个参与者带上了能感知人体皮肤反应的手环，他们发现城市所做的这些积极干预，确实能影响人们的感官和态度。研究发现40%的受访者在路过彩虹斑马线时更愉悦了，并且有高出60%的意愿希望在这里见他们的朋友。”
The design of rainbow channel is emotional but it is on the basis of rational research.Coincidentally, someone in other countries also tries to use iridescence to decorate the public space. From 2012, Davie and Bute Street in Vancouver paint the zebra crossings in 4 intersections iridescence. This experiment is proved to be successful. The study finds that 40% of visitors are happier when they walk by the rainbow zebra crossings and more than 60% of visitors would like to meet their friends here.
▼积极的城市干预能够影响人们的感官和态度，a positive urban intervention will influence the residents’ perception and attitude
The iridescent public area gives active hints to passers-by, building a unique and inclusive area. That’s why it is attached to great importance in community. The rainbow channel makes good use of iridescence, light and shadow. It gives people more active hints. The happy emotion is just what we want the rainbow channel bring to people.
The higher commercialization in a place, the lower connection is among people. In Shanghai, this modern commercial city, maybe it is wiser to build iridescent public space than to reject commercialization. Rainbow channel may be a good try.
