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. The color's unique impact stems from its heavy reliance on ultramarine pigment, creating a vivid and captivating visual experience. Klein specifically registered this color as a trademark to preserve its distinctive character and association with his artistic works. IKB is perceived as intensely pure and radiant, often evoking feelings of depth, transcendence, and boundless space. In color psychology, blue is often linked to trust, stability, and intelligence, while IKB, with its heightened intensity, takes on a more dramatic and expressive quality. Its distinct nature sets it apart from standard blue shades, making it a favorite in art, fashion, and design where a bold and captivating statement is desired.

The color #022EB2, also known as International Klein Blue, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value means that text rendered in this color against a white background (or vice versa) would have a very poor contrast ratio. According to WCAG guidelines, sufficient contrast is essential for readability. To improve accessibility, it's highly recommended to pair this dark blue with very light colors, such as white, light gray, or pale yellow, for text and interactive elements. Using tools to check color contrast ratios can ensure compliance with accessibility standards. Avoid using this color for crucial information or elements where readability is paramount. Additionally, providing alternative visual cues, like icons or text labels, can enhance the experience for users who might struggle to differentiate this color effectively. Proper use of ARIA attributes can also help convey information to assistive technologies.
