Pure black + zinc is the base. Pick an accent color to add warmth and brand identity to the health ring, active states, and chart highlights.
Classic ops/monitoring accent. Professional, calm, high contrast on dark backgrounds.
Safe, universally trusted. Standard for data visualization. Works everywhere but less distinctive.
Fresh, "everything's healthy" vibe. Great contrast on dark. Can conflict with green "ok" status badges.
Let the data speak. No accent — severity colors (red/amber/green) carry all the visual weight. Maximum clarity.
