The hex color #09458F, also known as Congress Blue, presents specific accessibility considerations for web design. Its dark hue results in a low luminance value, meaning it requires careful selection of foreground colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text against backgrounds. When using #09458F as a background, it's crucial to pair it with light text colors such as white (#FFFFFF) or very light shades of gray to meet these contrast requirements. Failure to do so can make the text difficult to read, especially for users with visual impairments. Additionally, it's essential to consider the overall design and avoid using this color for crucial interactive elements without providing clear visual cues, as this can affect the usability for users with cognitive disabilities.
