About International Klein Blue

International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. The color's visual impact comes from its heavy reliance on ultramarine and its purity. Klein sought to register this color as a trademark, and although he did not succeed in France, he did manage to register it in the United States. The unique visual effect of IKB stems from its matte finish, which allows for a greater saturation of the color by reducing light reflection. This matte effect is achieved by suspending the raw pigment in a synthetic resin, preserving the pigment's original qualities. It became the signature color of Klein's artworks, making it iconic in the art world.

The hex color #0922ab, also known as International Klein Blue, presents several accessibility challenges. Its deep, saturated hue results in low luminance, which can cause difficulties for users with visual impairments, particularly those with low vision or color blindness. The contrast ratio between #0922ab and white (#ffffff) is low, failing to meet WCAG (Web Content Accessibility Guidelines) standards for sufficient contrast. To improve accessibility, consider using a lighter background color to increase contrast. Text should be kept to a minimum size of 18px (or 14px bold). Always test color combinations with accessibility tools to ensure readability and usability for all users. Furthermore, avoid using color as the sole means of conveying important information; supplement it with text labels, icons, or patterns to accommodate individuals with color vision deficiencies. It is advisable to use a color contrast checker to ensure that the color combination meets accessibility guidelines.
