About International Klein Blue

International Klein Blue (IKB), represented by the hex code #0930AB, is a deep, vivid blue hue originally conceived by the French artist Yves Klein. Klein sought to capture the purest expression of blue, associating it with the intangible and infinite aspects of existence. He collaborated with a chemist to develop a unique matte synthetic resin that, when combined with ultramarine pigment, maintained the color's intensity and luminosity. IKB is more than just a color; it is a symbol of artistic innovation and a pursuit of spiritual depth through visual expression. Its unique formulation and association with Yves Klein elevate it to a distinguished position in the art world.

The contrast ratio of #0930AB against white is 13.18:1, which provides excellent readability for text and user interface elements. It meets WCAG AAA standards for text larger than 18pt or 14pt bold, ensuring accessibility for a wide range of users, including those with visual impairments. However, when used against black, the contrast ratio is only 1.60:1, which is insufficient for readability. Designers should prioritize using #0930AB on light backgrounds. In web design, avoid pairing #0930AB text on dark backgrounds or using it for small, non-bold text to maintain optimal accessibility and user experience. When using this color for decorative elements, ensure they are not crucial for conveying important information to comply with accessibility guidelines.
