Where Seaweed works
- Web & UI: Reads as an interactive accent: fills, hovers, focus rings. Keep body text in a darker neutral.
- Interiors: Use it where you want the eye to land: a front door, built-ins, or one bold wall.
- Fashion: One garment in this color carries an outfit; two starts to compete.
- Branding: A brand green signals freshness; deepen it for finance, brighten it for eco-consumer products.
- Web & UI: Use it decoratively for dividers, chart series, and illustration accents, and let neutrals carry the type.
- Branding: Best in a brand's supporting palette: packaging interiors, patterns, campaign accents.
