Ocean Blue A11y Accessibility Swatch
The Web Content Accessibility Guidelines sections 1.4.3 Contrast (Minimum) and 1.4.6 Contrast (Enhanced) define the required contrast ratio for compliance. The WCAG Level AA requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. WCAG Level AAA requires a contrast ratio of at least 7:1 for normal text and 4.5:1 for large text. The KendoReact library conforms to WCAG Level AA with the Default Ocean Blue A11y theme swatch coming with enabled contrast focus indicators (available as of version 6.0.1 of the Default Theme).
You can test the accessibility swatch in all KendoReact demos by choosing it in the Change Theme menu:
