Accessibility of the Customer.io palette

Of the 3 recorded colors, 1 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.
