About International Klein Blue

International Klein Blue, represented by the hexadecimal color code #0819A8, is a deep, intense shade of blue that holds a significant place in art history. Named after the French artist Yves Klein, who registered the color in 1957, IKB is characterized by its rich ultramarine pigment. Klein chose this particular hue for its ability to evoke a sense of boundless space and spiritual depth. The color is achieved through a specific combination of ultramarine pigment with a synthetic resin binder, which preserves the pigment's intensity. IKB is often associated with concepts such as infinity, spirituality, and the sublime, reflecting Klein's artistic vision. Its striking visual impact has made it a popular choice in various artistic and design applications.

The hex color #0819A8, also known as International Klein Blue, presents certain accessibility challenges. Its low luminance value (very dark blue) means it requires careful consideration when used as a foreground color. To ensure readability, it's crucial to pair it with a light background color that offers sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Failure to meet these ratios can make content difficult to perceive for users with visual impairments. Furthermore, avoid using this color for conveying crucial information without proper text labels or alternative visual cues, as colorblind users may struggle to differentiate it from other dark colors. Careful testing and validation with accessibility tools are highly recommended to guarantee an inclusive user experience.
