Color
An editorial greyscale ramp is the foundation. Chromatic color is a single punctuation moment per context — never a palette of accents, never twice where once will do.
Greyscale ramp
The neutral system. White is the default ground; black ink is the primary text, with cool greys for hierarchy.
The accent
Studio Blue #2749FF — the one punctuation accent. Use it once per context: a stat, a closing surface, one rule. Never decorative.

Secondary palette
Muted tones for accent backgrounds, category coding, and data-viz. One per context only — pair against ink or paper.
