Why it works and how to use it

Black & Terracotta is a monochromatic color palette tagged modern, dark, minimal. A monochromatic set: the same hue family from Obsidian down to Linen. Saturation is moderate, which keeps it flexible for both interfaces and print. The overall temperature is warm.

It works because the lightness range is wide (6% to 93%), which gives clear hierarchy between background, content and accents. Try it for websites, presentations and branding.

Background: Linen (#F4EEE8) is the lightest color, so it belongs on large surfaces.
Text: Obsidian (#0F0F0F) on #F4EEE8 gives 16.65:1, passing WCAG AAA.
Primary: Clay (#C8623F) is the most saturated mid-tone; use it for buttons and links (3.46:1 against the background, fine for UI elements).
Accent: Iron (#444444) for highlights, badges and hover states.

3 of 6 color pairs pass WCAG AA (4.5:1); the strongest is Obsidian on Linen at 16.65:1.
