About International Klein Blue

International Klein Blue, represented by the hex code #0529ae, is a deep, vivid blue hue renowned for its unique intensity. Developed by the French artist Yves Klein in collaboration with a Parisian paint dealer, this color was specifically formulated to retain its brilliance and luminosity, setting it apart from other blue pigments. Klein sought to capture the purest expression of blue, a color he associated with the boundless expanse of the sky and the sea. Officially registered as a trademark, International Klein Blue remains a distinctive and influential color in the realms of art, design, and fashion.

The hex color #0529ae, also known as International Klein Blue, presents several accessibility considerations for web developers. Its dark hue provides a strong contrast against white text, generally meeting WCAG guidelines for readability. However, when paired with darker backgrounds or text colors that lack sufficient contrast, it can pose challenges for users with low vision or color blindness. It is essential to test color combinations using accessibility tools to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Additionally, avoid relying solely on color to convey information; use text labels, icons, or patterns to provide alternative cues for users who may not be able to distinguish colors effectively. Careful consideration of these factors is crucial for creating inclusive and accessible web experiences.
