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. This specific shade was developed as part of Klein's pursuit to capture the purest expression of blue, aiming to evoke feelings of boundlessness and spirituality. In 1957, Klein officially patented the color under the name International Klein Blue. The key characteristic of IKB is its high saturation achieved through the suspension of pure color pigment in a synthetic resin, which retains the pigment's original quality and intensity. This distinctive blue has since been associated with art, minimalism, and modern design. Its use evokes feelings of depth, spirituality and an intellectual touch. IKB's unique visual impact has made it a popular choice in various creative fields, especially in contexts aiming to convey sophistication and innovation.

The hex color #032BB1, also known as International Klein Blue, presents significant accessibility challenges, particularly in web design. Its extremely low luminance (brightness) value means that text rendered in this color against a white background fails all levels of WCAG (Web Content Accessibility Guidelines) conformance. To ensure readability and usability for all users, including those with visual impairments, it's imperative to use a contrasting text color, such as white or a very light gray, when using #032BB1 as a background. Furthermore, relying solely on color to convey important information should be avoided. Providing alternative cues like text labels or icons can greatly improve the accessibility of content. It's crucial to consider these factors when incorporating #032BB1 into a design to create an inclusive and user-friendly experience.
