LINE emerged from the 2011 Tōhoku earthquake as a network-agnostic messenger, then became a cultural phenomenon through its character-driven sticker economy. Brown the bear, Cony the rabbit, and Sally the chick — designed by Kang Byung Mok — turned a chat app into a beloved IP empire spanning retail stores, cafes, and manga platforms across East and Southeast Asia.
The visual system is defined by LINE green (#06C755), universally rounded surfaces, and a warmth that feels like opening a sticker from a friend. Every element — from pill-shaped buttons to soft-shadow cards — inherits the approachable, character-first personality that made LINE more than a messenger.
LINE 诞生于2011年东日本大地震后的通信危机，由东京新宿的NHN Japan工程师打造，迅速席卷日本、台湾、泰国和印尼。姜炳默设计的布朗熊、可妮兔、莎莉鸡等角色让这款聊天应用成为一个跨越零售、咖啡馆和漫画平台的文化IP帝国。
视觉体系以LINE绿（#06C755）为锚点，所有界面元素均采用圆润造型，从药丸形按钮到柔阴影卡片，传递出一种"收到朋友贴图"般的亲切温暖。这不是冰冷的科技产品，而是一个有角色、有温度、有故事的数字世界。
