The color #2D47B9, a deep cerulean blue, presents some accessibility considerations for web design. Its relatively low luminance value means that it requires careful attention to contrast ratios, particularly when used for text or interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text against its background. When using #2D47B9 as a background, light text colors such as white (#FFFFFF) or very light shades of gray are often necessary to meet these standards and ensure readability for users with visual impairments. Conversely, using #2D47B9 as a text color requires a light background. Tools like contrast checkers can help verify sufficient contrast. It's also important to consider colorblindness. Simulate how the color appears to individuals with different types of color vision deficiencies to make sure that important information is not lost. Supplementing color with other visual cues, like icons or text labels, can further improve accessibility.
