Bright, glowing, and unapologetically loud, #cdef43 is a lime yellow that reads neon without tipping into harsh. Its high lightness gives it a warm, mellow edge that suits energy drinks, sports branding, and sale graphics. It works best as a bold accent or 10% pop against deep greens or charcoal, where its sparkle actually lands. As a hex code, it also supports black body text at strong contrast, so it stays readable in UI.
