About International Klein Blue

International Klein Blue, also known as IKB, is a deep blue hue first synthesized by the French artist Yves Klein. The color is renowned for its intense vibrancy and ultramarine-like appearance. Klein registered this color as a trademark in 1957, solidifying its place in art history. Its creation involved suspending pure color pigment in a clear synthetic resin, maintaining the pigment's brilliance. The color quickly became associated with Klein's artistic endeavors, particularly his monochrome paintings. IKB is used in art, fashion, and design to evoke feelings of depth, spirituality, and boundless space. The unique properties of the pigment continue to fascinate artists and designers worldwide. Its use is a symbol of innovation and the artist's quest for pure aesthetic expression.

The color #0532AE, a deep shade of blue known as International Klein Blue (IKB), presents considerable accessibility challenges, especially in web design. Its dark hue results in low contrast when paired with similarly dark colors, making it difficult for users with visual impairments to distinguish text or interactive elements. According to WCAG guidelines, sufficient contrast is crucial for readability. To ensure accessibility, IKB should be used with light colors like white (#FFFFFF) or pale yellow (#FFFFE0) to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Additionally, avoid using this color for crucial information if it is the only visual cue, as colorblind users may struggle to perceive it. Providing alternative cues, such as text labels or icons, enhances accessibility for a broader audience. Tools like contrast checkers can assist in verifying compliance with accessibility standards, ensuring a more inclusive user experience.
