Vitamin C
Also known as: Zambia , Hephaestus Gold , Jack-O , Aromango
As a medium take on orange, Vitamin C carries warm and inviting energy that suits friendly UI accents and children's products. Because it leans warm, balancing it with a blue keeps a palette from feeling one-note. Accessibility-wise, it needs a dark backdrop: 9.81:1 on black clears AA.

Where Vitamin C 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.
