About International Klein Blue

International Klein Blue, also known as IKB, is a deep shade of blue that was first mixed by the French artist Yves Klein. This specific hue, represented by the hexadecimal color code #0838AC, is renowned for its intense saturation and captivating visual effect. Klein registered this color as a trademark to maintain its unique identity within the art world. IKB is achieved through a specific formula that involves suspending pure ultramarine pigment in a synthetic resin, which allows the color to retain its brilliance and depth. The color's impact stems from its ability to evoke a sense of infinity and transcendence, which Klein sought to express through his monochrome paintings and sculptures.

The accessibility of #0838AC (International Klein Blue) should be carefully considered, especially in web design. Due to its dark hue, it's crucial to use it with light text or interface elements to ensure sufficient contrast, meeting WCAG guidelines for readability. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. For users with visual impairments, the color can pose challenges, so providing alternative color schemes or allowing users to adjust the display settings is essential. Avoid using this color for essential information without proper contrast. When using it for links or interactive elements, ensure there are additional visual cues to differentiate them from surrounding text. Thoroughly test the color combination with accessibility evaluation tools and with users with different visual abilities.
