Acid
Also known as: Acid Drop , Cyber Neon Green , Plastic Veggie , Hot Green
Few greens feel this vivid. Acid leans cool and calm and balanced, which points it toward outdoor gear and wellness brands. Match it with pink accents when the design calls for energy over calm. For accessible text, use it on black or near-black backgrounds (15.33:1, passes WCAG AA) rather than white.

RAL values are widely published approximations of the physical standard. For Pantone-adjacent workflows, match by eye against a physical fan deck. Pantone's values are proprietary and device-dependent, so we don't print lookups.
Where Acid 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: Reads as growth and sustainability, at home in wellness, food, and environmental brands.
- 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.
