Hex color #b4c914 graphic
Not a soft pastel, #b4c914 is a sharp citron yellow with a green edge, and it acts like one. Its high saturation and mid lightness give it an electric, glowing energy, which is why it shines as a 10% accent in sale banners and budget branding rather than a full background. Pair it with deep navy instead of plain white, and set black text on top; the hex code reaches about 11.3:1 contrast, well past WCAG AA for small type.
