The color #21447A, also known as Astronaut, presents specific accessibility considerations for web development. When used as a background color, it necessitates light-colored text to ensure sufficient contrast, meeting WCAG guidelines for readability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Color blindness should also be taken into account; individuals with protanopia, deuteranopia, or tritanopia may perceive this color differently. Therefore, relying solely on color to convey information is discouraged. Instead, supplementary cues such as text labels or icons should be used. Adequate testing with accessibility tools is crucial to ensure the design is inclusive and provides a satisfactory experience for all users, including those with visual impairments.
