How to use Peacock Blue
Peacock Blue is a deep, vivid tone (HSL 183°, 100%, 30%), which makes it a grounding background or strong accent. For text it passes WCAG AA for body text against a dark background (5.6:1) — safe for paragraphs, buttons and labels. When you do set type on it, use light lettering. Pair it with its complement (#9B0800) for a focal accent, or with its analogous neighbours (#009B56 and #00459B) for a quieter, harmonious feel.
