Klein Blue (IKB)

International Klein Blue is the singular ultramarine pigment Yves Klein formulated in 1957 to dissolve the boundary between viewer and artwork. Suspended in clear binder to preserve its powdery brilliance, IKB became the entire content of monochromatic canvases — color experienced as pure presence.

As a design system, Klein Blue distills that radical conviction into interface: an overwhelming chromatic field, restrained classical typography in white, and vast negative space that turns every screen into a meditative encounter with saturated blue.

国际克莱因蓝是法国艺术家伊夫·克莱因于1957年调配的超饱和群青色素——他将这种令人窒息的蓝色视为纯粹的"存在"本身，用它填满整幅画布，让观者融化在无限的蓝色场域中。

作为设计系统，克莱因蓝将这种极致的色彩信念注入界面：以压倒性的蓝色场域为底，搭配精炼的白色衬线字体与大量留白，将每一个屏幕转化为一场与饱和蓝的冥想式相遇。这不是装饰，而是色彩即内容。
