About International Klein Blue

International Klein Blue, represented by the hexadecimal color code #0B2FA9, is a deep, saturated blue hue renowned for its striking visual impact. Developed by the French artist Yves Klein, this color was specifically formulated to embody the artist's vision of pure, boundless space. It's achieved through a unique mixture of ultramarine pigment with a synthetic resin binder, which enhances its luminosity and depth. Klein patented the color in 1957, solidifying its place in art history. This color evokes feelings of vastness, spirituality, and transcendence. Its use in art and design is often intended to create a powerful, immersive experience for the viewer, drawing them into a world of color and emotion.

International Klein Blue (#0B2FA9) presents moderate accessibility challenges. Its dark hue provides decent contrast against white backgrounds, meeting WCAG AA standards for text and non-text contrast at a ratio of approximately 4.8:1. However, against darker backgrounds, readability decreases. To improve accessibility, pair it with very light colors like white or pale yellow. Avoid using it for small text or intricate details against similarly dark colors. Ensure interactive elements using this color have sufficient visual cues for users with visual impairments. Consider providing alternative high-contrast themes for enhanced usability. Using colorblindness simulators can further validate the color's accessibility for various visual impairments. Thoughtful color selection is key to inclusive design.
