About International Klein Blue

International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. This specific shade of blue was developed as part of Klein's search to find a color that best represented his concept of pure idea and spiritual space. Chemically, IKB is a matte version of ultramarine, achieved through a specific resin binder that allows the pigment to retain its intensity and visual impact. It has since become a recognized and iconic color in the art world, associated with creativity, depth, and transcendence. The color is often used to invoke feelings of serenity and contemplation. It is legally protected under a trademark in France in Yves Klein's name.

The color #082BAC, also known as International Klein Blue, presents some accessibility challenges, especially in web design. Its dark hue results in low contrast when paired with similarly dark colors, potentially making text or interactive elements difficult to read for users with visual impairments. To ensure accessibility, it's crucial to use this color with light backgrounds or text colors that provide sufficient contrast, adhering to WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. Tools like contrast checkers can assist in verifying compliance. Additionally, avoid relying solely on color to convey information, as users with color blindness may not be able to distinguish it. Providing alternative cues, such as text labels or icons, can improve the overall user experience for all individuals.
