Jet

Using #343434 creates a softer visual impact than pure black, which can feel harsh on high-contrast screens. This specific grey maintains a serious, grounded aesthetic while reducing eye strain, making it an ideal choice for modern dark mode interfaces and long-form reading backgrounds.

Jet works effectively as a foundation for high-contrast schemes when paired with crisp white or off-white text. For a more sophisticated mood, try combining this neutral with muted sage or dusty blue tones, as these cooling colors balance the heavy, dense weight of the dark grey.
