About International Klein Blue

International Klein Blue (IKB), with the hexadecimal color code #0823AC, is a deep blue hue first mixed by the French artist Yves Klein. Klein registered this color as a trademark in 1957, even though it was previously created with the help of a Parisian paint dealer, Edouard Adam. IKB's visual impact comes from its heavy reliance on ultramarine pigment, as well as Klein's technique of applying the paint in a way that maintains the pigment's pure intensity. This results in a vibrant and immersive color experience. Its distinctiveness has made it an iconic shade in the art world, celebrated for its unique and powerful visual qualities.

The color #0823AC, also known as International Klein Blue, presents significant accessibility challenges, particularly in web design. Its dark hue results in low contrast when paired with lighter text colors, potentially making content difficult to read for users with visual impairments. According to WCAG guidelines, sufficient contrast ratios are essential for readability. To ensure accessibility, it is crucial to use lighter text colors such as white or very light grays against the dark background of #0823AC. Tools for checking color contrast ratios should be used to verify compliance. Furthermore, relying solely on color to convey information should be avoided. Adding text labels or icons can provide alternative cues for users who may not be able to distinguish the color effectively.
