About International Klein Blue

International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein created IKB as part of his search to find a color that best represented his concept of pure idea. It is highly saturated and possesses a unique matte finish, due to the synthetic resin binder that Klein used to suspend the pigment. The visual impact of IKB lies in its purity and intensity, offering a sense of infinity and abstraction. Because the human eye is more sensitive to blue than other colors, the effect of IKB is particularly noticeable. It quickly gained recognition and became associated with Klein's artistic identity and his vision of art as a gateway to spiritual experience. The color is now trademarked, solidifying its place in art history and contemporary design.

The hex color #0624AE, known as International Klein Blue, presents significant accessibility challenges, especially concerning color contrast. When used as a background or text color, it's crucial to ensure sufficient contrast with the foreground or background, respectively, to meet WCAG (Web Content Accessibility Guidelines) standards. A light color, such as white or a very pale yellow, is generally recommended as the contrasting color to ensure readability for users with visual impairments. Tools like contrast checkers can be employed to assess the contrast ratio against WCAG thresholds. Given its high luminance, #0624AE may not be suitable for extended reading or critical interface elements. Therefore, careful consideration and testing with diverse user groups are essential to avoid excluding or negatively impacting users with visual impairments.
