International Klein Blue
About International Klein Blue
International Klein Blue, also known as IKB, is a deep blue hue first mixed by the French artist Yves Klein. This specific shade was developed as part of Klein's exploration of color as a medium, aiming to evoke a sense of unboundaried space and immersion. In 1957, Klein patented this color to maintain its unique identity. Chemically, IKB is a matte ultramarine pigment combined with a synthetic resin binder, which helps retain the color's intensity. Its powerful visual impact and connection to the art world make it a significant color in design and culture. The color's unique formulation enhances the perception of depth and saturation, distinguishing it from conventional blue shades.
The hex color #031DB5, representing International Klein Blue, presents significant accessibility challenges. Its extremely low luminance value of 3.25 makes it unsuitable for text or interactive elements on light backgrounds, as it fails WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. A contrast ratio of at least 4.5:1 is needed for normal text and 3:1 for large text. This color's contrast against white is far below this threshold. To use this color accessibly, it must be paired with a very light color. Consider using it sparingly for decorative purposes or logos, and always verify contrast ratios using accessibility tools. Ensure sufficient contrast by using a lighter hue like #ffffff to meet the required guidelines and provide an accessible experience for users with visual impairments. This consideration makes content usable for a wider audience.
