About International Klein Blue

International Klein Blue, represented by the hexadecimal color code #0B32A8, is a deep, intense blue hue renowned for its unique saturation and visual impact. This color was developed by the French artist Yves Klein in collaboration with a Parisian chemical company. Klein sought to create a blue that would capture the pure essence of the color, devoid of any distracting textures or sheens. The resulting pigment, known as International Klein Blue (IKB), was officially patented in 1957. It has since become an iconic color in the art world, celebrated for its captivating depth and emotional resonance. Its application extends beyond fine art, finding use in design, fashion, and even branding, where its distinctive and memorable quality is highly valued.

The hex color #0b32a8, also known as International Klein Blue, presents significant accessibility challenges, primarily due to its deep saturation and dark value. When used as a foreground color, it requires a very light background to meet the Web Content Accessibility Guidelines (WCAG) contrast ratios. Insufficient contrast can make text and interactive elements difficult or impossible for users with visual impairments to perceive. It is crucial to evaluate color combinations using accessibility tools to ensure compliance with WCAG 2.1 Level AA or AAA standards. Consider increasing the text size or using a thicker font weight to improve legibility. Avoid using this color for essential information or actions without careful consideration of its impact on users with disabilities. Providing alternative high-contrast themes or allowing users to customize color schemes can greatly enhance accessibility when utilizing this color.
