How to use Slate Color
Slate Color is a deep, muted tone (HSL 198°, 19%, 25%), which makes it a grounding background or strong accent. For text it passes WCAG AA for body text against a light background (10.0:1) — safe for paragraphs, buttons and labels. When you do set type on it, use light lettering. Pair it with its complement (#4C3B34) for a focal accent, or with its analogous neighbours (#344C47 and #34394C) for a quieter, harmonious feel.
