How to use Jasper Red
Jasper Red is a mid-tone, vivid tone (HSL 14°, 83%, 53%), which makes it a versatile mid-tone for accents, buttons or blocks. For text it passes WCAG AA for body text against a dark background (5.8:1) — safe for paragraphs, buttons and labels. When you do set type on it, use light lettering. Pair it with its complement (#24BCEB) for a focal accent, or with its analogous neighbours (#EB2458 and #EBB724) for a quieter, harmonious feel.
