International Klein Blue
About International Klein Blue
International Klein Blue, also known as IKB, is a deep shade of blue first mixed by the French artist Yves Klein. Klein registered this color as a trademark in 1957. The visual impact of IKB comes from its heavy reliance on ultramarine pigment and its matte, velvety surface texture. This particular blue is renowned for its intensity and purity, devoid of any modifying colorants. It evokes feelings of serenity and boundlessness, and it became a signature element in Klein's art. IKB has since transcended the art world, finding applications in fashion, design, and even branding, always retaining its association with creativity and innovation. Its hex code is #0024BD.
International Klein Blue (#0024BD) presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it requires very light text (ideally white or near-white) to ensure sufficient contrast for readability, meeting WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using this blue for text on a white background is generally not advisable due to poor contrast. In user interface design, avoid pairing it with similar dark colors. Consider using color contrast checkers to validate the accessibility of color combinations. Thoughtful application and testing are essential for inclusive design.
