International Klein Blue
About International Klein Blue
The color #0431B0, commonly referred to as International Klein Blue (IKB), is a deep, saturated blue hue. It was developed by the French artist Yves Klein in collaboration with a Parisian paint dealer, Edouard Adam, specifically for Klein's monochrome paintings. IKB's unique matte finish and intense saturation distinguish it from other blues, creating a visually arresting effect. Klein patented the color in 1957 to maintain its unique properties and ensure its exclusive use in his art. This vibrant blue has since become iconic, symbolizing artistic innovation and pushing the boundaries of color exploration.
The hex color #0431b0, also known as International Klein Blue, presents accessibility challenges due to its low luminance. When used as a foreground color, it requires careful consideration of the background color to ensure sufficient contrast for readability, especially for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text, as specified by WCAG guidelines. Combining this dark blue with light colors like white, yellow, or very light grays can improve legibility. Additionally, providing alternative text descriptions for images or graphical elements using this color is crucial for screen reader users. Developers should use color contrast analyzers to verify compliance with accessibility standards and make necessary adjustments to ensure inclusive design.
