About International Klein Blue

International Klein Blue, also known as IKB, is a deep blue hue first mixed by the French artist Yves Klein. This specific shade was synthetically created and then patented by Klein to maintain its uniqueness. It's defined not just by its color but also by its matte finish, which enhances the intensity and depth of the pigment. Chemically, IKB is a synthetic ultramarine pigment, a complex sulfur-containing sodium aluminosilicate. Its vibrant and almost ethereal quality made it a signature element in Klein's artwork, particularly his monochrome paintings. The color evokes feelings of infinity, spirituality, and the immaterial. In the art world, IKB has become synonymous with Klein's artistic vision, representing his exploration of pure color and its emotional impact.

The hex color #0220b2, also known as International Klein Blue, presents significant accessibility challenges. Its very dark hue results in a low contrast ratio when paired with lighter text, potentially making it difficult for users with visual impairments to read. According to WCAG guidelines, sufficient contrast is crucial for readability. To enhance accessibility, consider using a much lighter color for text or interactive elements placed on a #0220b2 background. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Tools like contrast checkers can help verify compliance. Additionally, avoid using color as the sole means of conveying information, as colorblind users may miss important cues. Providing alternative visual cues, such as icons or text labels, is essential for universal accessibility. Employing ARIA attributes can also improve the experience for users of assistive technologies.
