#30ff21 - Acid Reflux color

A vivid, electric lime-green with a bright, yellowish undertone, this color reads as high-energy and modern. It feels like fresh spring grass kissed by sunlight or a glowing LED accent — intense, youthful, and attention-grabbing. At full saturation it becomes almost neon, ideal for bold accents, call-to-action buttons, or sporty branding, though it can overwhelm large areas. It contrasts strongly with deep charcoal, navy, and pure black, and pairs cleanly with crisp white and muted neutrals.
