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 makes IKB so unique is not just its specific tone, but also the matte, synthetic resin binder used to maintain the color's intensity. This binder suspends the pigment and allows it to retain its brilliance, resulting in a visually striking and immersive color experience. The color evokes feelings of depth, infinity, and the vastness of the sea and sky. It is considered a pure and intense ultramarine. It is named after the French artist Yves Klein.

The contrast ratio of #032AB1 (International Klein Blue) with white text is quite low, at approximately 1.7:1. This falls far short of the WCAG guidelines for minimum contrast, which recommend a ratio of at least 4.5:1 for normal text and 3:1 for large text (18pt or 14pt bold). Therefore, using white text on an International Klein Blue background can cause readability issues, especially for users with visual impairments. For enhanced accessibility, consider using lighter shades of blue for the background or opt for significantly darker text colors like black or very dark gray. Testing your color combinations with accessibility tools is highly recommended to ensure compliance with WCAG standards and provide an inclusive user experience. Also using this color for important information and calls to action is discouraged.
