About International Klein Blue

International Klein Blue, represented by the hex code #081BAC, is a deep, vivid blue hue first mixed by the French artist Yves Klein. Klein registered this color as a trademark in 1957. It is known for its high saturation and perceived purity, meant to evoke a sense of boundlessness. The color is achieved using a specific ultramarine pigment that retains its intensity even when suspended in a binder. Because of its visual impact, International Klein Blue has been used extensively in art, fashion, and design to convey feelings of depth, spirituality, and the infinite. The color remains an important part of art history.

The hex color #081bac presents significant accessibility challenges for web content. Its very low lightness value results in extremely poor contrast against a standard white background. This fails WCAG (Web Content Accessibility Guidelines) contrast ratio requirements, making text and interactive elements difficult or impossible for users with visual impairments to perceive. To improve accessibility, it's crucial to pair #081bac with a much lighter color for text and interface elements. A lighter color will ensure sufficient contrast and meet accessibility standards. Use color contrast checking tools to verify that the contrast ratio meets the minimum requirements for WCAG AA or AAA compliance. Avoid using #081bac for critical information or interactive elements without careful consideration of color contrast.
