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, represented by the hex code #0117B3, stands out for its intense saturation and visual impact. Klein specifically created and registered this color to evoke a sense of boundlessness, depth, and pure color experience, thus becoming the main important concept in his artistic expression. It is achieved by suspending pure color pigment in a clear synthetic resin, maintaining its original brilliance. Because of its intensity, IKB has found use in various design fields but requires careful handling to avoid visual fatigue, especially in digital environments. Its uniqueness lies in its matte finish, which enhances the color's depth and makes it appear almost velvety. It is a color that demands attention and evokes a sense of wonder.

The color #0117B3, a deep and vibrant blue reminiscent of International Klein Blue, presents some accessibility challenges, particularly in web design. When using this color for text, it is crucial to ensure sufficient contrast with the background. A light background color, such as white or a very pale yellow, is recommended to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratio. Avoid pairing this blue with darker colors, as the low contrast can make text difficult to read for users with visual impairments. Consider using a contrast checker tool to verify that the chosen color combination meets accessibility requirements. Furthermore, when using this color in graphical elements, ensure that important information is not solely conveyed through color, but also through text labels or other visual cues. This is crucial for users with color blindness. Providing alternative text descriptions for images using this color can also enhance accessibility.
