How to use Sulphine Yellow
Sulphine Yellow is a mid-tone, vivid tone (HSL 46°, 63%, 46%), 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 (8.3:1) — safe for paragraphs, buttons and labels. When you do set type on it, use light lettering.
