Where Casper works
- Web & UI: A supporting-cast color for UI: chart fills, tags, empty-state illustrations — not text.
- Interiors: Soft and low-saturation — a candidate for full walls, where vivid colors overwhelm.
- Fashion: A wardrobe neutral: it anchors outfits and pairs with nearly any accent color.
- Branding: Craft and heritage material — coffee, leather goods, and premium packaging live here.
- Interiors: Strong for a whole room, excellent in doses: an accent wall, cabinetry, or a statement chair.
- Fashion: Wears best as the statement piece — a top, scarf, or shoes — against neutral basics.
