About International Klein Blue

International Klein Blue, represented by the hexadecimal color code #051BAF, is a deep and highly saturated shade of blue. Developed by the French artist Yves Klein, this color was specifically created to evoke feelings of depth, spirituality, and boundless space. Klein sought to capture the purest expression of blue, aiming for a color that transcends mere pigment and becomes a medium for emotion and transcendence. The color is often associated with art, creativity, and modern design. Its unique and intense hue has made it a popular choice in various artistic and commercial applications, signifying innovation and boldness. Due to its specific origin and the artist's intention, International Klein Blue carries a distinct cultural and artistic significance.

The color #051BAF, also known as International Klein Blue, presents considerable accessibility challenges. Its extremely low lightness value of approximately 3% results in very poor contrast against white text or backgrounds. This makes it difficult for individuals with visual impairments, including those with low vision or color blindness, to discern content accurately. According to WCAG guidelines, the contrast ratio of #051BAF against white is significantly below the minimum threshold of 4.5:1 for normal text and 3:1 for large text. To improve accessibility, it is crucial to pair this color with much lighter colors for text and interactive elements. Employing tools that check color contrast ratios is highly recommended to ensure compliance with accessibility standards and to provide a more inclusive user experience.
