About International Klein Blue (#0913AB)

International Klein Blue, represented by the hexadecimal color code #0913AB, is a deep and intense shade of blue. It's named after the French artist Yves Klein, who registered this specific hue in 1957. Klein used this vibrant blue extensively in his monochrome paintings and sculptures, aiming to evoke a sense of boundless space and the infinite. Chemically, IKB is created by suspending pure ultramarine pigment in a synthetic resin, which maintains the color's brilliance. In digital design, this color can be used to add depth and sophistication; however, due to its dark nature, it is essential to consider accessibility guidelines and ensure sufficient contrast when using it for text or interactive elements. Understanding its history and composition provides a richer context for its application in various creative fields.

The color #0913AB, also known as International Klein Blue, presents significant accessibility challenges, especially when used as text on a white background. Its low luminance value results in a poor contrast ratio, falling far short of WCAG (Web Content Accessibility Guidelines) recommendations for readability. To improve accessibility, consider using #0913AB sparingly for decorative elements rather than crucial textual content. When it is necessary to use it for text, pair it with a very light color such as white (#FFFFFF) or a highly contrasting yellow to ensure sufficient contrast. Providing alternative text descriptions for images that use this color is also important. Employing accessibility evaluation tools during the design phase can help identify potential issues and guide adjustments to meet accessibility standards, creating a more inclusive experience for users with visual impairments.
