#21AA64 Hex Color
Loud green built for bold accents
Closer to a ripe lime leaf than a deep forest green, #21aa64 is a loud, beaming shade of green. Its high saturation makes it a strong accent for calls to action, and it suits eco, pharmacy, and finance branding. Black text reads at about 7.0:1 on it, so small body copy stays accessible. Pair it with charcoal or a warm cream to keep it from overpowering a layout.
