General Information about International Klein Blue

International Klein Blue, also known as IKB, is a deep blue hue first mixed by the French artist Yves Klein. IKB's visual impact comes from its heavy reliance on ultramarine, as well as Klein's artistic use of the color. The color became Yves Klein's trademark, which he patented in 1957. It is a specific shade of blue achieved by suspending pure ultramarine pigment in a clear synthetic resin. The vivid color has a great visual impact, and it sets itself apart from other shades of blue. The color is not very common in nature, and is most often used in modern art and technological applications.

The hex color #0326ab, also known as International Klein Blue, presents some accessibility challenges, particularly in text-based applications. Its dark hue results in low contrast when paired with standard black text, rendering it difficult for users with visual impairments to read comfortably. To improve accessibility, it's crucial to use a light color for the text, such as white or yellow. Additionally, when used as a background, ensuring sufficient contrast with foreground elements is paramount. Tools like contrast checkers can help determine appropriate color pairings that meet WCAG (Web Content Accessibility Guidelines) standards, ensuring the content is perceivable, operable, and understandable by a wide range of users. Avoid relying solely on color to convey important information, as colorblind users may miss it. Consider using icons or text labels alongside color cues to enhance inclusivity.
