Why it works and how to use it
Lagoon Aqua & Evergreen is a vivid split color palette tagged cold, teal, green. A split scheme: Oat plays against Evergreen across roughly 110° of hue. 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 (17% to 77%), which gives clear hierarchy between background, content and accents. Try it for websites, presentations and branding.
- Background: Oat (#D1DEAD) is the lightest color, so it belongs on large surfaces.
- Text: Evergreen (#0D4A1F) on #D1DEAD gives 7.32:1, passing WCAG AAA.
- Primary: Aqua (#34EBFF) is the most saturated mid-tone; use it for buttons and links with a border or a darker shade for contrast.
- Accent: Spruce (#006354) for highlights, badges and hover states.
