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 remarkable intensity and unique matte finish are achieved through a specific formula that involves suspending pure ultramarine pigment in a synthetic resin. Klein registered this formula under the name 'International Klein Blue' in 1957. This vibrant color transcends mere aesthetics; it embodies Klein's artistic exploration of the infinite and the immaterial. Klein sought to capture the essence of pure space, evoking a sense of boundlessness. The color has become synonymous with his art and legacy. Its unique depth and intensity have inspired artists, designers, and scientists alike.

The color #0832AC, also known as International Klein Blue, presents significant accessibility challenges, particularly for users with visual impairments. Its low lightness value (relative luminance of approximately 0.02) means that text rendered in this color requires very light or white foreground colors to achieve sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to ensure readability. Using a dark color like #0832AC for text or important UI elements without careful consideration of contrast can exclude users and hinder their ability to perceive and interact with content effectively. Designers should rigorously test color combinations using contrast checkers to meet accessibility standards. Furthermore, avoid using this color alone to convey important information; always provide redundant cues like text labels or icons.
