About International Klein Blue

International Klein Blue, represented by the hexadecimal color code #0525AF, is a deep and intense shade of blue closely associated with the artist Yves Klein. He patented this specific hue, which he considered to be the purest and most perfect expression of blue. Characterized by its ultramarine-like appearance, it is created using a synthetic ultramarine pigment bound in a resin that allows the color to retain its vividness. The color's perceived depth and luminosity contribute to its unique and captivating aesthetic. Its boldness makes it a powerful choice in various applications, including art, design, and fashion, where it can convey a sense of sophistication and modernity.

The hex color #0525AF, representing International Klein Blue, presents significant accessibility challenges. Its extremely dark hue results in very low contrast against light backgrounds, making it difficult for users with visual impairments to read text or distinguish elements using this color. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. #0525AF likely fails to meet these criteria against standard white backgrounds. To improve accessibility, consider pairing it with very light shades, ideally white or very pale yellows. Alternatively, use a significantly lighter shade of blue or a different color altogether to ensure sufficient contrast and readability for all users. Thoroughly testing with accessibility tools is essential to confirm compliance.
