About International Klein Blue

International Klein Blue, often referred to as IKB, is a deep blue hue first mixed by the French artist Yves Klein. He sought to create a blue that would best express his art and what he was trying to convey. This specific shade of blue was synthetically made and then patented by Klein. The color is achieved by using a matte, synthetic resin binder which suspends the color pigment and allows the pigment to maintain its color characteristics. The vividness of IKB comes from its lack of reflection; its deep saturation captures and holds the viewer's gaze, evoking a sense of boundlessness. It has become iconic in art and design, representing depth, spirituality, and the infinite.

The color #0E1BBC, also known as International Klein Blue, presents some accessibility challenges. Its dark hue results in a low contrast ratio when paired with lighter text colors, which can make it difficult for users with visual impairments to read content. According to WCAG guidelines, sufficient contrast between text and background is crucial for readability. Using white or very light shades of yellow or green as text on this blue background improves legibility. For crucial interface elements, consider a larger font size or a bolder text weight to further enhance contrast and readability. Furthermore, avoid using this color as the sole indicator of functionality; provide alternative cues such as text labels, icons, or patterns to ensure that interactive elements are perceivable to all users, including those who are colorblind or using assistive technologies.
