Cardano's official palette spans blue: Cardano Blue (#0033AD) and Cardano Light Blue (#1A44B8). Against white the ratios run from 8.19:1 to 10.11:1, so every value meets the 4.5:1 contrast ratio WCAG AA requires of normal-size body text.

Accessibility of the Cardano palette

Of the 2 recorded colors, 2 reach the WCAG 2.1 AA ratio of 4.5:1 against a white background — the threshold normal-size body text must meet. Colors below that line are not failures of the palette: they remain valid as fills carrying white text, as large text at the 3:1 threshold, and as borders, icons, and other non-text elements, which SC 1.4.11 also holds to 3:1. A logotype set in such a color is exempt from the requirement entirely.
