How to use Cha
Cha is a deep, muted tone (HSL 38°, 29%, 33%), which makes it a grounding background or strong accent. For text it passes WCAG AA for body text against a light background (6.6:1) — safe for paragraphs, buttons and labels. When you do set type on it, use light lettering. Pair it with its complement (#3C4E6C) for a focal accent, or with its analogous neighbours (#6C423C and #666C3C) for a quieter, harmonious feel.
