The hex color #2E4CB8, also known as Cerulean Blue, presents some accessibility challenges, especially for users with visual impairments. Its relatively low luminance value of approximately 0.11 means that it requires careful consideration when choosing text and background colors. According to WCAG (Web Content Accessibility Guidelines) standards, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text against a background. Given the darkness of Cerulean Blue, it is best paired with very light colors like white (#FFFFFF) or very light yellows (#FFFFE0) to ensure sufficient contrast. Using darker shades or colors closer in luminance value may result in text that is difficult to read, impacting usability and accessibility. Furthermore, avoid using this color as the sole indicator for interactive elements; supplement it with labels, icons, or other visual cues to accommodate users with color vision deficiencies.
