About International Klein Blue

International Klein Blue, also known as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein registered this vivid shade as a trademark in 1957. What distinguishes IKB from other blues is its particularly intense saturation achieved through the addition of a synthetic ultramarine pigment suspended in a clear resin. This unique formulation allows the pigment to maintain its brilliance without being dulled by the binder. Klein employed IKB extensively in his monochrome paintings and sculptures, aiming to evoke a sense of boundless space and pure emotion. The color has since become iconic, symbolizing innovation, depth, and artistic vision. Its cultural impact extends beyond art, influencing design, fashion, and even technology.

The hex color #0614AE, also known as International Klein Blue, presents considerable accessibility challenges, particularly in web design. Its dark hue results in low luminance, creating insufficient contrast against lighter backgrounds, especially white. According to WCAG guidelines, adhering to minimum contrast ratios is crucial for ensuring readability and usability for individuals with visual impairments. Text or interactive elements rendered in #0614AE against a white or light-colored background may not meet the necessary contrast requirements. To mitigate these issues, designers should pair #0614AE with significantly lighter colors to achieve adequate contrast, or consider using it sparingly for purely decorative elements. Tools like contrast checkers can help evaluate compliance with accessibility standards and suggest appropriate color pairings to enhance the user experience for all users, including those with disabilities.
