Jack-O
Also known as: Aromango, Vitamin C, DodgeRoll Gold, Clementine Earring
Jack-O is a medium, vivid orange that reads as warm and inviting. It shines in fitness brands and autumn palettes. Set it against a blue accent when you want the combination to pop. For accessible text, use it on black or near-black backgrounds (9.66:1, passes WCAG AA) rather than white.

Where Jack-O 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.
