The hex color #213F77, also known as Astronaut, presents some accessibility considerations for web development. Its relatively low lightness value means it requires careful pairing with text and other elements to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text against its background. Using #213F77 as a background color necessitates light-colored text (e.g., white or very pale shades) to meet these criteria. For elements like buttons or interactive components, ensure that hover, focus, and active states also maintain adequate contrast. Tools like contrast checkers can help verify compliance with accessibility standards, enhancing the user experience for individuals with visual impairments. Moreover, avoid relying solely on color to convey information; supplement color cues with text labels or icons.
