About International Klein Blue

International Klein Blue (IKB), represented by the hexadecimal color code #071DAD, is a deep, vivid blue hue first mixed by the French artist Yves Klein. Klein patented this particular shade of blue in 1957 to ensure its preservation and association with his artistic work. The color's intensity arises from its high saturation and purity, lacking any visual undertones of green or red. IKB is often perceived as conveying feelings of depth, transcendence, and boundlessness, and it has become a symbol of artistic innovation and the exploration of color's emotional impact. Its unique depth makes it memorable and recognizable.

The hex color #071DAD, also known as International Klein Blue, presents significant accessibility challenges, particularly in web design. Its dark hue results in a very low contrast ratio against standard light backgrounds, failing WCAG (Web Content Accessibility Guidelines) standards for text and non-text contrast. To ensure inclusivity, using #071DAD for text requires a very light foreground color, like white or a near-white shade, to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. When using this color for decorative elements, ensure they are not essential for understanding content or functionality. Employing tools to check color contrast is crucial. Consider providing alternative high-contrast themes or color palettes to cater to users with visual impairments or color vision deficiencies. Thoroughly test the color combination with assistive technologies to guarantee a positive user experience. Prioritizing accessibility makes digital content usable for everyone, regardless of their abilities.
