Sulphur
Also known as: Brownish Yellow, Mustard, Grass Daisy, Lionhead
A vivid yellow with a sunny and uplifting character, Sulphur works beautifully for kids' apps and summer palettes. A blue counterpart from the complementary harmony gives it the most tension. Accessibility-wise, it needs a dark backdrop — 9.73:1 on black clears AA.

Where Sulphur works
- Web & UI: Best as a button fill, badge, or accent — pair it with white text only at large sizes, and check contrast.
- 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.
- Branding: High-energy brand material: strong for food, fitness, and youth-facing marks — use sparingly in UI.
- Web & UI: A supporting-cast color for UI: chart fills, tags, empty-state illustrations — not text.
- Branding: A secondary brand color by nature: it supports a stronger primary and shines in illustration.
