About International Klein Blue

International Klein Blue (IKB), with the hex code #0716AD, is a deep, vivid blue pigment first synthesized in 1956 by the French artist Yves Klein. Klein sought to create a blue that embodied his artistic vision of boundless space and immateriality. He collaborated with a chemist to develop a unique formula that suspends the pure color pigment, ultramarine, in a synthetic resin, maintaining the pigment's intensity and brilliance. IKB is not just a color; it's a cultural phenomenon, representing artistic innovation and the pursuit of visual transcendence. The color's saturation and depth have made it popular in art, fashion, and design, often used to evoke feelings of awe, wonder, and the infinite. The color has become a trademarked part of Yves Klein's artistic legacy.

The color #0716AD, also known as International Klein Blue, presents significant accessibility challenges. Its very low lightness value (close to black) means that text or interactive elements using this color as a background require extremely light foreground colors to achieve sufficient contrast. According to WCAG guidelines, the contrast ratio should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. Using white (#FFFFFF) as a foreground color would be necessary, but even then, careful testing is crucial to ensure readability for users with visual impairments. Avoid pairing this color with any shades of gray or other dark colors, as they will likely fail accessibility standards. Consider using it sparingly as a background for purely decorative elements where the contrast requirements are less stringent, or explore alternative, lighter shades of blue that offer better contrast ratios.
