#adff2f - Chestnut Shell color

This bright, electric yellow-green reads like neon lime—vibrant, zesty and unmistakeably energetic. It evokes fresh spring grass, citrus peel, and a lively, youthful spirit. Use it as an accent to draw attention, in branding for active or eco-forward products, or as a high-visibility highlight against dark neutrals. Paired with charcoal, navy or deep purple it pops; used large it can feel overwhelming, so reserve it for buttons, icons, or small decorative elements.
