International Klein Blue

#0020B3

General Information

International Klein Blue, represented by the hex code #0020B3, is a deep and highly saturated shade of blue. It is named after the French artist Yves Klein, who patented the color in 1957. Klein sought to create a blue that was as pure and intense as possible, believing that it could evoke a sense of boundlessness and spirituality. The color is achieved by suspending ultramarine pigment in a synthetic resin, which allows the pigment to retain its brilliance and depth. IKB has become a symbol of artistic innovation and has been widely used in art, fashion, and design. Its unique character and visual impact make it a popular choice for creating bold and memorable statements. The color is registered under the name IKB (International Klein Blue).

The hex color #0020B3, also known as International Klein Blue, presents significant accessibility challenges, especially in web design. Its deep, saturated nature results in low contrast against lighter backgrounds, potentially making text and interactive elements difficult to read for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using #0020B3 for text or crucial interface components against a white or light-colored background would likely fail to meet these standards. Therefore, it's essential to pair this color with very light or very dark shades to ensure sufficient contrast. Additionally, providing alternative styling options and adhering to ARIA attributes can further enhance the accessibility of web content using this color, catering to a wider audience and promoting inclusivity.
