Why it works and how to use it

Aqua Marine is a vivid monochromatic color palette tagged ocean, cold, white. A monochromatic set: the same hue family from Gunmetal down to Frost. 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 (15% to 93%), which gives clear hierarchy between background, content and accents. Try it for websites, presentations and branding.

Background: Frost (#E0FBFC) is the lightest color, so it belongs on large surfaces.
Text: Gunmetal (#0B3C42) on #E0FBFC gives 11.14:1, passing WCAG AAA.
Primary: Cadet (#00A8B5) is the most saturated mid-tone; use it for buttons and links with a border or a darker shade for contrast.
Accent: Powder Blue (#98E2E8) for highlights, badges and hover states.

2 of 6 color pairs pass WCAG AA (4.5:1); the strongest is Frost on Gunmetal at 11.14:1.
