The hex color #0B478D, also known as Congress Blue, presents some accessibility challenges, especially when used as a background or text color. Its relatively low luminance necessitates careful consideration of contrast ratios to ensure readability for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text against its background. When pairing #0B478D with text, a light color like white or a very pale yellow would be ideal to achieve sufficient contrast. Using darker text colors against this shade of blue may render the text unreadable for many users. Furthermore, avoid using this color to convey important information solely through color, as colorblind users may not be able to perceive it. Always provide alternative cues, such as text labels or icons, to ensure inclusivity.
