About International Klein Blue

International Klein Blue, often referred to as IKB, is a deep blue hue first mixed by the French artist Yves Klein. It's renowned for its intense saturation and visual impact. Klein registered this color as a trademark in 1957, solidifying its association with his art. The unique matte finish of IKB, achieved through a special synthetic resin, enhances its perceived depth and luminosity, making it appear almost otherworldly. The hex code #0916ab represents this particular shade within the digital color spectrum. Because of its saturation, it's crucial to use this color thoughtfully in design, considering its impact on visual balance and accessibility. Its intense color has made the color famous in the art world.

The hex color #0916ab, also known as International Klein Blue, presents some accessibility challenges, particularly for text and user interface elements. Its low lightness value (approximately 5%) means it requires very light text (white or near-white) to achieve sufficient contrast for readability. According to WCAG (Web Content Accessibility Guidelines), the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA conformance. When using #0916ab as a background, ensure that the text color provides adequate contrast. Tools like WebAIM's contrast checker can help verify compliance. Consider also providing alternative color schemes or a user-adjustable color palette to accommodate users with visual impairments or color blindness. Over-reliance on this color can exclude users if contrast guidelines aren't meticulously followed. It's crucial to test the color combination in various contexts and with real users to ensure optimal accessibility.
