About International Klein Blue
International Klein Blue (IKB), represented by the hexadecimal color code #0239A8, is a deep ultramarine blue hue. It was developed and patented by the French artist Yves Klein, who sought to create a blue that captured the essence of the sky and the sea. IKB is renowned for its intense saturation and matte finish, which minimizes light reflection, allowing the viewer to focus on the color itself. Chemically, IKB is a synthetic ultramarine pigment, a powdered, artificial version of the natural mineral lapis lazuli. Yves Klein registered IKB as a trademark in 1957, making it a signature element of his artistic works, particularly his monochrome paintings and sculptures. This unique color has since become a symbol of modern art and a significant cultural reference.
The color #0239A8, or International Klein Blue, presents significant accessibility challenges, particularly concerning color contrast. When used as a foreground color, it requires a very light background to meet WCAG (Web Content Accessibility Guidelines) standards for readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Due to its dark nature, this hue may not be suitable for extensive textual content. It’s crucial to assess the contrast ratio with foreground elements meticulously. Using color contrast tools can help determine if the combination is accessible to individuals with visual impairments. Consider using it sparingly for decorative elements or larger graphical components, and always provide alternative visual cues, such as icons or text labels, to ensure inclusivity. Adequate testing with users with different visual abilities is paramount to ensure accessibility compliance.
