Gunjō is a deep, muted tone (HSL 209°, 48%, 28%), which makes it a grounding background or strong accent. For text it passes WCAG AA for body text against a light background (9.2:1) — safe for paragraphs, buttons and labels. When you do set type on it, use light lettering. Pair it with its complement (#6B4726) for a focal accent, or with its analogous neighbours (#266B69 and #26286B) for a quieter, harmonious feel.
