About International Klein Blue

International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. The color's unique vibrancy comes from its heavy reliance on ultramarine pigment. Klein registered this color as a trademark, solidifying its identity within the art world. IKB is known for its matte finish, which enhances the color's intensity and makes it appear even more saturated. The color gained prominence in Klein's monochromatic paintings and sculptures, which aimed to evoke a sense of infinity and spiritual depth. Beyond the art world, IKB has found applications in fashion, interior design, and graphic design, often used to create a bold and striking visual statement. Its distinctive quality makes it instantly recognizable and highly impactful.

The hex color #0B20BF, also known as International Klein Blue, presents some accessibility challenges, especially in web design. Its high intensity can cause eye strain if used excessively for large blocks of text or backgrounds. When using this color, it's crucial to ensure sufficient contrast with foreground text or elements. A lighter color, such as a pale yellow or white, would provide better readability and reduce visual fatigue. Tools like contrast checkers can help determine if the color combination meets accessibility standards like WCAG (Web Content Accessibility Guidelines). Avoiding overuse and pairing it with appropriate contrasting colors can make designs more inclusive and user-friendly, particularly for individuals with visual impairments. Consider offering alternative color themes to accommodate different user preferences and accessibility needs. For buttons or interactive elements, use hover states or focus indicators to provide clear visual cues. Testing with users is essential to validate that designs are accessible and enjoyable for everyone.
