General Information about International Klein Blue

International Klein Blue, often referred to as IKB, is a deep shade of blue first mixed by the French artist Yves Klein. Klein patented this color in 1957. The visual impact of IKB comes from its heavy reliance on ultramarine pigment, as well as Klein's artistic use of the color on canvas. The hue is a vivid shade of blue that appears to 'pop' due to its purity and depth. It is often associated with art, innovation, and sophistication. Its unique characteristics make it a captivating color that continues to inspire artists and designers. It has a significant role in the color palette, and is still being used up to this day.

The hex color #0016b4, a deep and intense blue, presents several accessibility considerations for web development. Its low luminance value means that it requires careful attention to contrast ratios. When used as a background color, it demands very light text to ensure readability, meeting WCAG (Web Content Accessibility Guidelines) AA or AAA standards. Conversely, as a text color, it necessitates a very light background. Using contrast checking tools is crucial to verify compliance. Furthermore, avoid using this color for essential UI elements like links or buttons without sufficient contrast, as users with visual impairments may struggle to identify them. Semantic HTML and ARIA attributes can further enhance accessibility, especially when using this color in complex UI components. Consider providing alternative high-contrast themes to accommodate users with different visual needs, ensuring an inclusive user experience. Thoughtful application of this color, paired with rigorous testing, is key to maintaining accessibility.
