About International Klein Blue

International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein created IKB in collaboration with a Parisian paint dealer, Edouard Adam, to achieve a very pure and intense blue that would best evoke his concept of the infinite and immaterial. The color's intensity is achieved through the use of a synthetic ultramarine pigment suspended in a clear, matte synthetic resin. This allows the pigment to maintain its brilliance and depth without being dulled by traditional binding agents. Klein patented IKB in 1957, ensuring its association with his artwork and artistic vision. The color has since become iconic, representing creativity, depth, and the boundless nature of the imagination.

The color #083AA8, also known as International Klein Blue, presents some accessibility challenges, especially in web design. Due to its dark hue, it requires careful consideration of color contrast to ensure readability for users with visual impairments. When used as a background color, it is crucial to pair it with light-colored text (e.g., white or a very pale yellow) to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Insufficient contrast can make content difficult or impossible to read for individuals with low vision or color blindness. Therefore, thorough testing with accessibility tools is essential to validate the color combination's compliance with accessibility guidelines. Avoid using this color for essential information or interactive elements if adequate contrast cannot be achieved.
