General Information about International Klein Blue

International Klein Blue, often referred to as IKB, is a deep shade of blue that was developed by the French artist Yves Klein. The visual impact of IKB comes from its heavy reliance on Ultramarine pigment, as well as Klein's matte, synthetic resin binder, which suspends the color pigment and allows the pigment to maintain as much of its original qualities as possible. Yves Klein registered this color as a trademark in 1957, even though the color was created earlier. This color has a unique, almost velvety appearance due to its light absorbing quality, making it visually striking and memorable. IKB is often associated with art, creativity, and innovation, and has been used in various artistic and commercial applications.

The color #0520AE, also known as International Klein Blue, presents several accessibility considerations for web developers. Its very dark hue results in a low luminance value, requiring careful selection of foreground colors to ensure 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 against its background. White (#FFFFFF) or very light shades of yellow or cyan would be suitable choices. Using this color for text is not advisable due to readability issues. If #0520AE is used for interactive elements like buttons or links, make sure that the focus state is clearly visible and meets contrast requirements. It's also important to consider users with color vision deficiencies. Tools can simulate how this color appears to individuals with different types of color blindness to verify that crucial information is still discernible. Avoid relying solely on color to convey information; instead, use labels, icons, or patterns to supplement the visual cues.
