The hex color #011DB3, a deep and vibrant blue, presents significant accessibility challenges, especially when used as a foreground color against a white background. Its low luminance value results in poor contrast, making it difficult for individuals with visual impairments to discern text or graphical elements. To ensure accessibility, it's crucial to pair this color with light colors. According to WCAG guidelines, the contrast ratio should be at least 4.5:1 for normal text and 3:1 for large text. Using tools to evaluate contrast ratios is highly recommended to avoid accessibility issues and provide an inclusive user experience. Also avoid using this color for crucial UI elements without proper testing.
