About International Klein Blue

International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein patented this color, which is renowned for its intense saturation and unique matte finish. The color's impact comes from its ability to evoke feelings of openness, spirituality, and boundlessness. Klein sought to capture the essence of pure color, unburdened by form or representation, to create a profound emotional experience for the viewer. IKB is achieved using a specific formula of ultramarine pigment suspended in a synthetic resin binder, which preserves the color's vibrancy and prevents it from dulling over time. This particular shade of blue has found its way into various fields, including art, design, and fashion, due to its striking visual appeal and historical significance.

The color #071EAD, a deep and saturated blue, presents significant accessibility challenges. Its low luminance value results in poor contrast against light backgrounds, making text and other visual elements difficult to read for users with visual impairments. To ensure accessibility, it is crucial to use this color with very light backgrounds or to pair it with high-contrast text colors like white or light yellow. Following WCAG guidelines for contrast ratios is essential when employing this color in user interfaces. The minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text must be met to comply with accessibility standards. Additionally, avoid using this color as the sole indicator of interactive elements, such as links or buttons, as colorblind users may not be able to distinguish them. Providing alternative visual cues, such as underlines or icons, is necessary to ensure that all users can perceive and interact with the content effectively.
