Why it works and how to use it

Emerald Cadet & Peacock is a vivid dark, analogous color palette tagged dark, cold, black. Analogous neighbors on the wheel (Peacock, Cadet, Glacier) give it a natural, low-tension flow. Saturation runs high, so use the brightest color sparingly and let the others carry the surface area. The overall temperature is cool.

It works because the lightness range is wide (6% to 90%), which gives clear hierarchy between background, content and accents. Try it for dark-mode interfaces and gaming.

Background: Glacier (#CEE7FF) is the lightest color, so it belongs on large surfaces.
Text: Obsidian (#03071E) on #CEE7FF gives 15.67:1, passing WCAG AAA.
Primary: Peacock (#0B525B) is the most saturated mid-tone; use it for buttons and links (6.95:1 against the background, fine for UI elements).
Accent: Cadet (#1B998B) for highlights, badges and hover states.

3 of 6 color pairs pass WCAG AA (4.5:1); the strongest is Obsidian on Glacier at 15.67:1.
