The hex color #234F75, also known as Chathams Blue, presents some accessibility challenges, especially when used as a background color for text. Its relatively low luminance value means that text needs to be a light color to ensure sufficient contrast. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. When using #234F75, ensure to pair it with colors like white (#FFFFFF) or very light grays to meet these standards. Testing with accessibility tools is crucial to verify compliance. Avoid using it with darker text colors, as it can make the content difficult to read for users with visual impairments. Consider the needs of colorblind users and provide alternative cues where color is used to convey information.
