About International Klein Blue

International Klein Blue (IKB), also known as #0617AE, is a deep, intense blue hue that was developed by the French artist Yves Klein. Klein sought to create a blue that would express the purest expression of blue, capturing the vastness and immateriality of the color. He collaborated with a chemist to develop a synthetic ultramarine pigment that maintained its intensity and luminosity when suspended in a binder. IKB is more than just a color; it is an artistic statement, representing the infinite and the spiritual. Its unique and captivating nature has made it a popular choice in art, fashion, and design, appreciated for its depth and ability to evoke powerful emotions. IKB's chemical composition is a synthetic ultramarine pigment, specifically a finely ground ultramarine blue mixed with a synthetic resin binder. This combination helps maintain the color's intensity and prevents it from becoming dull or muted, which is crucial for preserving the intended artistic effect.

International Klein Blue, with its deep and intense hue, presents specific accessibility considerations in web design. Its low luminance value (approximately 4%) means that it requires very light text (white or near-white) to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using dark text on an IKB background is not accessible. When using this color for interactive elements like buttons or links, ensure that hover, focus, and active states provide clear visual cues that meet accessibility standards. Also, consider providing alternative text descriptions for images or icons that use IKB, allowing users with visual impairments to understand their purpose. Thoughtful application of IKB can enhance user experience while maintaining accessibility.
