Kelp
Also known as: Freshwater Marsh, Lunar Green, Amazon Depths, Castle Stone
Part of the green family, Kelp pairs a rich base with a grounded and restorative presence — ideal for finance apps and outdoor gear. Set it against a blue accent when you want the combination to pop. On white it reads clearly at 8.31:1 contrast — safe for body text under WCAG AA.

Where Kelp works
- Web & UI: Dark enough for body text and icons on white backgrounds — it passes WCAG AA as-is.
- Interiors: Strong for a whole room, excellent in doses: an accent wall, cabinetry, or a statement chair.
- Fashion: A wardrobe neutral: it anchors outfits and pairs with nearly any accent color.
- Branding: Reads as growth and sustainability — at home in wellness, food, and environmental brands.
- Web & UI: A supporting-cast color for UI: chart fills, tags, empty-state illustrations — not text.
- Fashion: Wears best as the statement piece — a top, scarf, or shoes — against neutral basics.
