White as a sheet

Origin

Imagine the stark contrast of a person’s face, usually flushed with life, suddenly drained of all color. What could be whiter, more unblemished, than a freshly laundered bedsheet? This vivid comparison likely emerged from the everyday observation of how profound shock, intense fear, or sudden illness could blanch a person's complexion. The simile isn't rooted in some grand historical event or ancient ritual; instead, its power comes from its simple, universal relatability. It taps into the visual shock of seeing someone's healthy glow instantly vanish, leaving them looking utterly devoid of vitality, as stark and flat as the fabric itself.
