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. Klein registered this color as a trademark in 1957. The striking visual impact of IKB comes from its intense saturation, largely because of the matte, synthetic resin binder in which the pigment is suspended, allowing the pigment to maintain its brilliance. IKB is more than just a color; it's a statement, an embodiment of art and innovation. It has been widely used in art installations and remains a significant point of reference in color theory and art history. The intense hue evokes feelings of depth, transcendence, and a touch of the infinite.

International Klein Blue (#0032B4) presents some accessibility challenges due to its dark hue. When used as a background color, it requires light-colored text (white or very pale shades) to ensure a sufficient contrast ratio, meeting WCAG (Web Content Accessibility Guidelines) standards for readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. For users with visual impairments, especially those with low vision, insufficient contrast can make text illegible. When using this color for interactive elements like buttons or links, ensure that the color change on hover or focus provides enough visual distinction to be noticeable for all users, including those with color blindness. Avoid pairing it with very dark or similarly saturated colors. Using color contrast tools can help determine appropriate pairings and ensure accessibility compliance.
