Acid

Also known as: Acid Drop, Cyber Neon Green, Plastic Veggie, Hot Green

As a medium take on green, Acid carries calm and balanced energy that suits 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.

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, empty-state illustrations — not text.
  • Branding: A secondary brand color by nature: it supports a stronger primary and shines in illustration.
