The color #1913B7, a dark blue, presents significant accessibility challenges, primarily due to its low luminance. When used as a background color, it requires very light text to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between the text and background should be at least 4.5:1 for normal text and 3:1 for large text. This dark blue shade will likely fail these requirements with most standard text colors, necessitating careful selection of a very light, almost white, text color. In user interface design, avoid using this color for critical interactive elements unless accompanied by clear visual cues beyond color alone, such as icons or text labels. Consider providing alternative high-contrast themes to accommodate users with visual impairments. Proper testing with accessibility tools is crucial to validate compliance with accessibility standards.
