Why it works and how to use it
Lime Zest is a vivid monochromatic color palette tagged modern, white, green. All four colors sit within 4° of hue, so the scheme reads as one color explored across light and dark. These are bold, punchy colors that need generous white space around them.
It works because the lightness range is wide (11% to 95%), which gives clear hierarchy between background, content and accents. Try it for websites, presentations and branding.
- Background: Ivory (#F9FFE5) is the lightest color, so it belongs on large surfaces.
- Text: Raisin (#1F2E0A) on #F9FFE5 gives 14.08:1, passing WCAG AAA.
- Primary: Butter (#D9F99D) is the most saturated mid-tone; use it for buttons and links with a border or a darker shade for contrast.
- Accent: Kelly Green (#84CC16) for highlights, badges and hover states.
