International Klein Blue
About International Klein Blue
International Klein Blue, often abbreviated as IKB, is a deep shade of blue that was developed and patented by the French artist Yves Klein. This particular hue is renowned for its intense saturation and unique visual impact. Klein sought to capture the purest expression of blue, believing it conveyed boundless space and spirituality. The color was synthetically created by mixing ultramarine pigment with a special resin binder, which preserved the pigment's vibrancy and texture. Officially registered in 1957, IKB has become synonymous with Klein's artistic vision and has been widely adopted across various creative fields, from art and design to fashion and architecture. Its unique depth and luminosity continue to captivate and inspire.
The hex color #0215b2, also known as International Klein Blue, presents significant accessibility challenges, especially in web design. Its extremely low luminance value of 0.006 makes it difficult to achieve sufficient contrast with lighter colors typically used for text or interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text. Using this dark blue as a background or text color necessitates employing very light foreground colors like white or light yellow to meet these standards. Even then, careful testing with accessibility tools is crucial to ensure readability for users with visual impairments. Furthermore, it's important to avoid using this color as the sole indicator for interactive elements, such as links, as color blindness can prevent users from perceiving these distinctions. Providing supplementary cues like underlines or icons will drastically improve the usability.
