靛藍隧道的線路導視

A text-free guide concept map of an urban underground pedestrian tunnel, with three-layered color strips of indigo, fog blue and light blue extending along the wall. The light strips turn at the fork in the road, showing a continuous space and a clear path when viewed from an oblique angle.

無文字的城市地下步行隧道導視概念圖，以靛藍、霧藍和淺青三層色帶沿牆面延伸，燈帶在岔路口轉向，俯視斜角展示連續空間與清晰路徑。
