International Klein Blue
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. This color was specifically developed to capture the intensity and brilliance of lapis lazuli. It is renowned for its ultramarine depth and its ability to evoke a sense of boundless space and emotion. The color was officially patented by Klein in 1957. Its unique matte finish further enhances its visual impact, setting it apart from other blues. The specific formula involves a synthetic ultramarine pigment suspended in a clear, synthetic resin binder, allowing the pigment to maintain its pure, unadulterated intensity. It is still used for art purposes today.
International Klein Blue (#0328A6) presents significant accessibility challenges, particularly concerning color contrast. Its dark hue necessitates careful pairing with lighter text or interface elements to ensure readability for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #0328A6 as a background, developers should prioritize white or very light yellow text to meet these standards. Employing color contrast analyzers during the design process is crucial to verify compliance and prevent accessibility barriers. Furthermore, providing alternative visual cues, such as underlines or icons, can enhance usability for users who have difficulty distinguishing colors. It is also useful to provide a colorblindness simulator to ensure the design is accessible to all users.
