Toss reduced Korean money-transfer to three taps and built a visual language to match: one defining blue, ash-warm neutrals, Pretendard at four weights, and conversational Hangul copy that treats users like friends, not bank customers. Every pixel serves the single-action-per-screen philosophy — generous whitespace around money amounts, flat blue pill buttons, and a warm green checkmark that says "done" before the subway doors close.
Toss（토스）是韩国金融科技的代名词——创始人李承健在首尔江南区用"三次点击完成转账"重新定义了移动支付体验。视觉语言围绕一个标志性蓝色 #3182F6 展开，搭配灰暖中性色面板、Pretendard 字体的四种字重，以及用日常韩语而非银行术语写成的对话式文案。整个设计系统像首尔地铁换乘一样高效：打开、转账、确认、关闭，一切在下一班列车到站前完成。
