About International Klein Blue

International Klein Blue, represented by the hexadecimal color code #0115A7, is a deep, vivid shade of blue known for its unique intensity. Developed by the French artist Yves Klein, this color was specifically created to evoke feelings of boundlessness and immersion. Klein worked with a Parisian paint supplier to formulate a matte, ultramarine pigment that retained its brilliance even when suspended in a binding medium. He then patented the process in 1960. The color is often associated with art, spirituality, and depth, and it has become a symbol of Klein's artistic vision, marking a significant contribution to the world of modern art. It is perceived as a color that embodies the infinite and the ethereal.

The hex color #0115A7, also known as International Klein Blue, presents some accessibility challenges, particularly in web design. Its dark hue means that text rendered in this color requires a very light background to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. When using #0115A7 for text, careful selection of background colors is crucial to meet these standards. Conversely, using #0115A7 as a background color necessitates light-colored text. It is important to test the color combination using accessibility tools to confirm compliance with accessibility standards, ensuring that the content is usable for individuals with visual impairments.
