About International Klein Blue

International Klein Blue, also known as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein patented this color in 1957. What sets IKB apart is its intense saturation, achieved by suspending pure color pigment in a clear synthetic resin, which allows the pigment to maintain its brilliance. IKB is more than just a color; it's a statement, an artistic medium, and a symbol. Its intense, almost overwhelming presence makes it visually striking and memorable. In digital applications, its hexadecimal code #0914AB identifies it, allowing designers and artists to accurately reproduce this unique and impactful color.

International Klein Blue (#0914AB) presents accessibility challenges due to its dark hue. When used as a background, it necessitates very light text (white or near-white) to ensure sufficient contrast for readability, meeting WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. Avoid pairing it with similarly dark colors as it can cause visual strain. Consider providing alternative color schemes or allowing users to adjust the color settings to accommodate different visual needs. Thoughtful implementation is crucial to ensure inclusive and accessible design for all users, especially those with visual impairments. Using a color contrast checker is highly advisable during the design process.
