About International Klein Blue

International Klein Blue, often abbreviated as IKB, is a deep shade of blue first mixed by the French artist Yves Klein. Its visual impact comes from its heavy reliance on ultramarine pigment, as well as Klein's matte, synthetic resin binder, which allows the pigment to retain its intensity and brightness. The color is a specific hue of blue, and is considered a vivid and intense pure color, often associated with depth and infinity. Klein registered this color as a trademark in France in 1957, although its widespread use means enforcement is difficult. It's frequently seen in modern art, fashion, and design, adding a striking visual element and often evoking feelings of tranquility or wonder. The intense saturation and historical context contribute to its unique appeal.

The hex color #092bab, representing International Klein Blue, presents specific accessibility considerations for web development. When used as a background color, it requires careful selection of foreground text colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Given its dark nature, #092bab necessitates light-colored text to meet these standards. White (#ffffff) and light shades of yellow or grey are suitable choices. Tools like contrast checkers can verify compliance. Avoid pairing it with other dark colors, as this will render content illegible for users with visual impairments. Consider providing alternative color schemes that offer greater contrast and are user-selectable. Employing ARIA attributes to enhance the semantic structure of the content can also aid assistive technologies in interpreting and conveying information accurately.
