It is important to note that the visual perception of this color can vary depending on the display device and ambient lighting conditions.

The hex color #0A2AAA, a deep, vibrant blue reminiscent of International Klein Blue, presents several accessibility considerations for web developers. Its relatively low luminance value means it requires careful pairing with contrasting colors to ensure readability, especially for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #0A2AAA as a background, light colors like white, light grey, or pale yellow should be employed for text to meet these contrast requirements. Conversely, using dark text on a #0A2AAA background could render the text illegible for many users. Developers should use contrast checking tools to verify compliance. It's crucial to avoid using this color for conveying critical information without proper contrast, as this would exclude a significant portion of users. Additionally, consider providing alternative color schemes to accommodate users with specific visual preferences or needs.
