About International Klein Blue

International Klein Blue, often abbreviated as IKB, is a deep shade of blue first mixed by the French artist Yves Klein. Klein sought to develop a blue that best expressed his concepts of art and the infinite. What sets this color apart is its vivid intensity and its almost ultramarine quality. IKB is achieved by using a matte, synthetic resin binder that allows the pigment to retain its brilliance and purity. This distinct formulation creates a surface that seems to absorb light, making it appear particularly captivating and immersive. It's become a widely recognized and appreciated color in the art world and beyond.

The hex color #0917ab, a deep and saturated blue, presents some accessibility challenges, particularly concerning color contrast. When used as a foreground color, it requires careful pairing with a background color that provides sufficient contrast to ensure readability for individuals with visual impairments. 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. Therefore, #0917ab would ideally be paired with very light shades of yellow, cream, or even white to meet these standards. Using this color for crucial text or interactive elements on darker backgrounds should be avoided unless very light text is used. In situations where #0917ab is used for decorative elements, it's essential to ensure that it doesn't interfere with the user's ability to perceive and understand critical content. Additionally, providing alternative visual cues, such as icons or labels, can further enhance accessibility for all users, especially those with color vision deficiencies.
