#CFD9DE Hex Color

Zen works effectively as a background for technical interfaces because it offers enough contrast for black text while remaining easy on the eyes. It mimics a professional, muted aesthetic that avoids the harshness of pure white while maintaining a clean look.

Use #cfd9de alongside charcoal or deep slate tones to ground the color and maintain a professional visual hierarchy. It can appear washed out if placed directly against bright white, so pairing it with darker elements helps define the layout.
