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. What makes this color unique is its intense saturation and matte finish, achieved by suspending pure ultramarine pigment in a synthetic resin. Klein registered this color as a trademark to protect its unique identity and artistic significance. IKB is more than just a color; it represents artistic expression, innovation, and a departure from traditional color palettes. It's frequently associated with modern art, intellectual pursuits, and a bold, confident aesthetic. The color's impact is largely due to its ability to evoke a sense of depth and infinite space, drawing the viewer into a meditative and immersive experience.

International Klein Blue (#052FAF) presents potential accessibility challenges. Its relatively low luminance value of 14 makes it difficult to achieve sufficient contrast against light backgrounds. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #052FAF for text or interactive elements, ensure careful pairing with a sufficiently light background to meet these contrast requirements. If achieving adequate contrast is problematic, consider lightening the color or opting for a darker shade to enhance readability and usability for individuals with visual impairments. Thoroughly test color combinations using accessibility evaluation tools to ensure compliance with accessibility standards and provide an inclusive user experience.
