How to use Deep Slate Green

Deep Slate Green is a deep, muted tone (HSL 174°, 47%, 13%), which makes it a grounding background or strong accent. For text it passes WCAG AA for body text against a light background (14.3:1) — safe for paragraphs, buttons and labels. When you do set type on it, use light lettering. Pair it with its complement (#2F1114) for a focal accent, or with its analogous neighbours (#112F1D and #11232F) for a quieter, harmonious feel.
