About International Klein Blue

International Klein Blue (IKB), with the hex code #082EA4, is a deep ultramarine blue hue renowned for its intensity and visual impact. It was developed by the French artist Yves Klein in collaboration with a Parisian paint dealer, and patented in 1957. Klein sought to capture the purest expression of blue, believing it to embody the infinite and spiritual. IKB achieves its unique vibrancy through the use of a synthetic resin binder, which allows the pigment to retain its brilliance and depth. This color has become iconic in the art world and is frequently used in modern design to evoke feelings of creativity, sophistication, and depth. Its distinctive quality makes it easily recognizable and memorable.

The color #082EA4, also known as International Klein Blue, presents significant accessibility challenges due to its low lightness value. When used as text, it will likely fail WCAG contrast requirements against white or other light backgrounds. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to ensure readability for users with visual impairments. Using this color for text requires careful consideration of the background color to achieve sufficient contrast. In user interface design, avoid using this color alone to convey important information; supplement it with text labels or icons. Additionally, provide alternative color schemes that offer better contrast for users who may have color vision deficiencies. Testing with accessibility tools is crucial to ensure compliance with accessibility standards.
