About International Klein Blue

International Klein Blue, also known as IKB, is a deep blue hue first mixed by the French artist Yves Klein. It is renowned for its intense saturation and matte finish, setting it apart from standard blues. Klein registered this color as a trademark to preserve its unique identity and association with his artwork. The color is achieved through a specific formula involving ultramarine pigment mixed with a synthetic resin binder. This particular combination intensifies the blue's visual impact, giving it a distinct and almost ethereal quality. The hex code for International Klein Blue is #0216A0, and it finds use in both fine art and design, often to evoke a sense of depth and emotion.

International Klein Blue (#0216A0) presents significant accessibility challenges, particularly concerning color contrast. Its dark hue necessitates very light text or foreground elements to meet WCAG (Web Content Accessibility Guidelines) standards for sufficient contrast ratios. For instance, using white text on this background generally provides adequate contrast. However, designers must avoid pairing it with mid-tone colors, as this will likely fail accessibility checks. In practical terms, avoid using this color for important UI elements like buttons or form fields unless the text is carefully chosen and tested. Tools like contrast checkers can help ensure compliance, promoting inclusivity for users with visual impairments. It's best used sparingly as an accent color in larger designs with areas of high contrast, not for elements critical to usability.
