Physical inactivity has been an increasing sub-health condition. Nudging people to participate in physical activities consequently becomes a public health priority. This study aims to showcase how color as a design factor can work to nudge city travelers to take on walking. Alongside the color effect, this experimental study incorporates another two design factors, namely, priming and social norms. The findings suggest that the use of colored sidewalks stimulate perceptual salience and individuals' moods, thereby increasing travelers' desire for walking. Priming tourists with sneakers and displaying social norms were also found to increase travelers’ interest in walking. The current study is innovative in incorporating color in the design of walkable routes in cities for its visitors. It is the first to apply nudges into the context of walkable city design oriented towards tourists.

缺乏运动已成为一种日益严重的亚健康状况。因此，促使人们参与体育活动成为公共卫生的优先事项。本研究旨在展示颜色作为设计因素如何推动城市旅行者开始步行。除了颜色效果，本实验研究还结合了另外两个设计因素，即启动和社会规范。研究结果表明，彩色人行道的使用会刺激感知显着性和个人情绪，从而增加旅行者步行的欲望。研究还发现，为游客穿运动鞋并展示社会规范可以提高游客步行的兴趣。目前的研究在为游客设计城市步行路线时采用了创新的颜色。
