Dark Mode Foundation

Dark mode requires surface layering (not just black) and carefully desaturated accent colors. This palette provides the base layer system: near-black backgrounds, dark mid-surfaces, and a single structured blue for hierarchy and interactive states.

A dark interface foundation palette that moves from near-black ink through structured dark layers to an active cobalt. Avoids true black in favor of dark blue-gray surfaces with depth.

Why this set works

A layered dark surface system in deep cobalt-gray — built for interfaces, not decoration.

Editorial direction

Collections should do more than group swatches. Each one should read like a usable design direction with a clear emotional lane and a real application surface.

This detail route is the missing layer between a generic palette gallery and a convincing design reference. It gives the set a specific point of view.
