Jack-O
Also known as: Aromango , Vitamin C , DodgeRoll Gold , Clementine Earring
Jack-O holds a medium position in the orange range and reads as warm and inviting. You'll see it used for 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, and empty-state illustrations, but not text.
- Branding: A secondary brand color by nature: it supports a stronger primary and shines in illustration.
