The hex color #154A77, also known as Chathams Blue, presents certain accessibility considerations, particularly in web design. Its relatively dark hue means it requires careful selection of foreground colors to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #154A77 as a background color, lighter shades of text such as white (#FFFFFF) or very light grays are generally necessary to meet these standards. Tools are available to calculate the contrast ratio between two colors, allowing developers to verify compliance. Furthermore, consider users with color vision deficiencies; relying solely on color to convey information is discouraged. Providing alternative visual cues, like text labels or icons, alongside color, can enhance accessibility. When using this color in interactive elements, ensure that hover, focus, and active states are clearly distinguishable to benefit all users, including those with visual or motor impairments.
