The hex color #0A478E, also known as Congress Blue, presents some accessibility challenges, especially when used as a background color for text. Its relatively low lightness value means that text needs to be a very light color to provide sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to meet AA standards. Using a color contrast checker is crucial to ensure adequate contrast. For example, white text (#FFFFFF) on a #0A478E background provides good contrast, while darker text colors may fail accessibility checks. In user interface design, consider providing alternative themes or color palettes to accommodate users with visual impairments, such as options for high contrast modes. Also, avoid using this color as the sole indicator of interactive elements, as colorblind users may not be able to distinguish them. Supplement color cues with text labels or icons.
