How to use Ukon
Ukon is a mid-tone, vivid tone (HSL 45°, 72%, 56%), 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 (11.0:1) — safe for paragraphs, buttons and labels. When you do set type on it, use dark lettering. Pair it with its complement (#4069E0) for a focal accent, or with its analogous neighbours (#E06740 and #B9E040) for a quieter, harmonious feel.
