About International Klein Blue

International Klein Blue (IKB), also known as #0229B2, is a deep, intense blue hue that was developed by the French artist Yves Klein. He wanted to create a blue that was as pure and vibrant as possible, a blue that could capture the essence of the sky and the sea. The color is achieved through a specific formula that includes a synthetic resin binder, which allows the pigment to retain its brilliance and intensity. IKB has become a significant color in the art world, often associated with concepts of spirituality, infinity, and the sublime. It is an extremely pure color that captures the vision of Klein.

International Klein Blue, with its deep and saturated hue, presents certain accessibility considerations for web design. When using this color for text, it's crucial to ensure sufficient contrast against the background to meet WCAG (Web Content Accessibility Guidelines) standards. A light background color, such as white or a very pale yellow, is generally recommended to achieve adequate contrast and readability. Avoid pairing it with dark or similarly saturated colors, as this can strain the eyes and make it difficult for users with visual impairments to discern the text. Furthermore, when used in interactive elements like buttons or links, ensure that there are clear visual cues beyond color alone to indicate the element's function, catering to users with color blindness. Using patterns, text labels, or changes in shape on hover can improve usability for everyone.
