In the RGB color model, IKB's composition is approximately 4, 23, 170, resulting in a striking and captivating visual impact.

The hex color #0A39AA, also known as International Klein Blue, presents some accessibility challenges, especially in web design. Its dark hue necessitates careful consideration of color contrast. When used as a background, it demands very light text to ensure readability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text to meet WCAG (Web Content Accessibility Guidelines) standards. This color might not be suitable for critical interactive elements unless accompanied by sufficient visual cues and proper ARIA attributes. For users with low vision, providing options to adjust color schemes becomes crucial. Designers should test color combinations using accessibility evaluation tools to identify and rectify potential usability issues, ensuring inclusivity for all users.
