About International Klein Blue

International Klein Blue, represented by the hex code #0812ad, is a deep and intense shade of blue renowned for its unique visual impact. It was specifically developed by the French artist Yves Klein in collaboration with a Parisian paint supplier. Klein sought to capture and maintain the purest expression of blue, believing it represented the boundless and immaterial essence of space. The color is characterized by its high saturation and minimal undertones, making it stand out distinctly from other blues. Its application extends across various creative fields, including art, design, and fashion, where it is used to evoke a sense of depth, infinity, and the sublime. The color is so unique that it has been patented and its formula is a trade secret.

The hex color #0812ad, also known as International Klein Blue, presents significant accessibility challenges, particularly concerning color contrast. When used as text against a white background, or conversely, white text against this blue, the contrast ratio is very low. This can make it difficult for users with visual impairments, such as those with low vision or color blindness, to read the content. To improve accessibility, it's crucial to pair this color with lighter shades of yellow, white or create sufficient contrast with adjacent colors. Using a color contrast checker tool can help ensure compliance with WCAG (Web Content Accessibility Guidelines) standards, aiming for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. It’s also important to avoid relying solely on color to convey information, as this can exclude users who are unable to distinguish between certain colors. Providing alternative visual cues, such as icons or text labels, can enhance usability for all users.
