About International Klein Blue

International Klein Blue (IKB), with the hexadecimal code #092DAB, is a deep shade of blue that is known for its intensity and striking appearance. It was developed by the French artist Yves Klein in collaboration with a Parisian paint manufacturer. Klein sought to create a blue that would capture the purest expression of blue, reminiscent of the sky and the sea. IKB is characterized by its matte finish, which enhances the depth and luminosity of the pigment. The color is achieved by suspending pure ultramarine pigment in a synthetic resin, which allows the pigment to retain its brilliance without being dulled by the binding agent. Yves Klein famously registered IKB as a trademark in 1957, solidifying its place in art history.

The color #092DAB, also known as International Klein Blue, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it necessitates very light text (white or near-white) to ensure sufficient contrast for readability, meeting WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using online contrast checkers is crucial to verify compliance. Furthermore, avoid using #092DAB as the sole indicator of interactive elements like links or buttons, as colorblind users may struggle to differentiate them. Providing alternative visual cues, such as underlines or icons, is essential. Careful consideration of text size and font weight can also improve readability against this deep blue hue. Thorough testing with diverse user groups is recommended to validate accessibility.
