About International Klein Blue

International Klein Blue, represented by the hex code #002EB4, is a deep and intense shade of blue renowned for its unique visual impact. Developed by the French artist Yves Klein, this color was specifically created to embody the artist's vision of pure, boundless space. Chemically, it is achieved through a specific formulation of ultramarine pigment. In the RGB color model, it consists of 0 red, 46 green, and 180 blue. This combination results in a distinctive hue that is neither a typical sky blue nor a navy blue, but something entirely its own. Its use extends beyond the art world, finding applications in design, fashion, and even branding where a powerful and evocative color is desired.

The hex color #002EB4, also known as International Klein Blue, presents some accessibility challenges, particularly concerning color contrast. When used as a foreground color for text, it's crucial to ensure sufficient contrast against the background. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Given its deep hue, #002EB4 may not meet these contrast requirements when paired with lighter backgrounds such as white or light gray. To enhance accessibility, consider using darker backgrounds or employing techniques like text shadows or outlines to improve readability. It's always advisable to use color contrast checkers to verify compliance with accessibility standards and ensure that content is perceivable to users with visual impairments. Also avoid using this color as the sole means of conveying important information.
