About International Klein Blue

International Klein Blue, represented by the hexadecimal color code #081AAC, is a deep and intense shade of blue known for its unique vibrancy and impact. This particular blue was developed by the French artist Yves Klein in collaboration with a Parisian paint dealer, aiming to capture the purest and most evocative expression of blue. Klein registered this color as a trademark in 1957, solidifying its place in art history. The color's unique matte finish enhances its intensity, giving it a mesmerizing quality that draws viewers in. It's often associated with concepts of infinity, spirituality, and the boundless nature of the universe, reflecting Klein's artistic vision of transcending the physical world.

The hex color #081AAC, also known as International Klein Blue, presents significant accessibility challenges, especially when used for text or interactive elements. Its dark hue results in a low contrast ratio against light backgrounds, making it difficult for users with visual impairments to discern content effectively. To ensure inclusivity, it's crucial to pair this color with very light foreground colors, such as white or pale yellow, to achieve a contrast ratio that meets WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Moreover, avoid using #081AAC for essential UI components like buttons or links without sufficient contrast, as this can exclude users with low vision or color blindness. Providing alternative styling options or allowing users to customize color schemes can further enhance accessibility.
