About International Klein Blue

International Klein Blue, often referred to as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein registered this color as a trademark in 1957, though the trademark's validity has been debated. Specifically, International Klein Blue is a deep ultramarine blue achieved through the addition of a synthetic ultramarine pigment to a polyvinyl acetate binder. The vividness of IKB stems from its ability to absorb light, creating a strong visual impact. It's more than just a color; it's a statement. Its creation and registration as a trademark, though controversial, mark a significant moment in art history and color theory. The color has found applications in various creative fields, from painting and sculpture to fashion and design. It remains a powerful and recognizable hue, often associated with innovation and artistic expression.

International Klein Blue (#0713AD) presents some accessibility challenges, particularly in text applications. Its dark hue necessitates careful consideration of contrast ratios. When used as a background color, it's crucial to pair it with very light text (white or very light shades of yellow or gray) to ensure sufficient contrast for readability, ideally meeting WCAG (Web Content Accessibility Guidelines) AA or AAA standards. Conversely, using this color for text on a white or light background would likely fail accessibility checks due to insufficient contrast. Designers should test color combinations using accessibility checkers to confirm compliance. Furthermore, consider users with visual impairments; providing alternative styling options or high-contrast themes can significantly improve their experience. Avoid using this color for essential interactive elements without adequate visual cues or text labels, as users with colorblindness may struggle to identify them.
