LEGO is primary colors snapped together — the most intuitive visual language of construction ever created. Red, yellow, blue, and green sit on a medium-gray baseplate beside the rounded stud grid and instruction-manual line art. The brand says "build anything" and means it.
The design language is cheerful engineering: a precise 8mm stud grid, bold saturated primaries, chunky rounded forms, and the satisfying click of things fitting together. Nothing is elegant, nothing is moody — everything is toybox bright, matte plastic, and snap-together confident.
乐高是一种被卡扣咬合的原色语言——或许是人类发明过最直观的"搭建"视觉系统。红、黄、蓝、绿四色块落在中灰色底板之上，圆形凸点整齐排列，说明书式的线描图清晰到连小朋友都能照着拼。它用最简单的色彩说出最自信的一句话：Build anything——什么都能搭。
乐高的视觉哲学是"快乐的工程学"：8 毫米凸点网格作为底层秩序，饱和度拉满的原色作为情绪，圆角方块（砖块本身的形状）作为基础语汇。没有柔和粉彩，没有优雅衬线，没有玻璃质感——一切都是磨砂塑料的手感、鲜亮的配色，以及两块砖咔哒扣上时那一声令人上瘾的清脆。
