How to use Green Blue
Green Blue is a deep, vivid tone (HSL 183°, 89%, 31%), which makes it a grounding background or strong accent. For text it passes WCAG AA for body text against a dark background (5.5:1) — safe for paragraphs, buttons and labels. When you do set type on it, use light lettering. Pair it with its complement (#970F09) for a focal accent, or with its analogous neighbours (#099756 and #094A97) for a quieter, harmonious feel.
