About International Klein Blue

International Klein Blue, represented by the hex code #071FAD, is a deep and intense shade of blue. It was created by the French artist Yves Klein, who registered it as a trademarked color in 1957. Klein sought to capture the purest expression of blue, aiming to convey a sense of boundless space and immateriality. The pigment's unique formulation involves a synthetic ultramarine pigment suspended in a clear synthetic resin, allowing the color to retain its brilliance and depth. This color is celebrated for its visual impact and its ability to evoke emotional responses, ranging from serenity to profound contemplation. International Klein Blue has seen widespread use in various artistic and design contexts.

The hex color #071FAD, also known as International Klein Blue, presents several accessibility considerations for web developers. Its dark hue means that it requires a light text color to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between the text and background should be at least 4.5:1 for normal text and 3:1 for large text. Using a tool to check the contrast ratio is highly recommended. Employing a lighter color such as white or a very light yellow would meet these criteria and help users with visual impairments or color blindness read content effectively. Furthermore, providing alternative text descriptions for images that incorporate this color is crucial for users who cannot perceive the color visually. Consider using CSS to ensure text remains legible even if the background color fails to load correctly. It is generally recommended to avoid relying solely on color to convey important information.
