The hex color #283B64, also known as Rhino, presents specific accessibility considerations, especially in web design. Its dark nature implies that it requires light-colored text to ensure sufficient contrast for readability. A contrast ratio of at least 4.5:1 is recommended for normal-sized text, as specified by the Web Content Accessibility Guidelines (WCAG). For larger text (14pt bold or 18pt regular), a contrast ratio of 3:1 is acceptable. Insufficient contrast can lead to difficulties for users with visual impairments, including those with low vision or color blindness. Tools like contrast checkers can help designers assess the contrast ratio between text and background colors. Furthermore, relying solely on color to convey information should be avoided; supplementary cues like text labels or icons are necessary to ensure inclusivity.
