About International Klein Blue

International Klein Blue (IKB), represented by the hexadecimal color code #032CB2, is a deep, intense blue hue first mixed by the French artist Yves Klein. Klein patented this particular shade of blue to ensure its uniqueness and association with his artwork. IKB is renowned for its remarkable saturation, achieved through the use of a synthetic ultramarine pigment. The color's intense vibrancy makes it visually striking and emotionally evocative, often associated with feelings of depth, transcendence, and artistic expression. Its chemical composition primarily consists of sodium polysulfide and aluminosilicate. IKB has become an iconic color in art, fashion, and design, symbolizing creativity and innovation. Its distinctive character has cemented its place in the history of art and visual culture, continuing to inspire artists and designers worldwide.

The color #032CB2, also known as International Klein Blue, poses significant accessibility challenges due to its deep saturation and low luminance. When used as a foreground color against a white background, it often fails to meet WCAG (Web Content Accessibility Guidelines) requirements for contrast ratio. This means that users with visual impairments, such as low vision or color blindness, may struggle to read text or distinguish important elements. To improve accessibility, consider using a lighter shade of blue or pairing it with a very light color such as white or yellow to achieve a sufficient contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Ensuring adequate contrast is crucial for providing an inclusive and user-friendly experience for all website visitors. Always test color combinations with accessibility tools to verify compliance with accessibility standards.
