About International Klein Blue

International Klein Blue, also known as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein patented this color in 1957. What sets IKB apart is its intense saturation and matte finish, which maximizes the impact of the blue pigment. Chemically, IKB is a synthetic ultramarine pigment. In the art world, Klein used IKB to achieve a specific aesthetic in his monochrome paintings and sculptures. The color aims to evoke a sense of boundlessness, depth, and the infinite. The color isn't typically perceived in nature, which can create a feeling of surrealism when used in artworks. Beyond art, International Klein Blue has found its way into various design fields, including fashion, interior design, and graphic design, often used to convey creativity and innovation.

The hex color #0714ad, also known as International Klein Blue, presents significant accessibility challenges, particularly for users with visual impairments. Its very low luminance value of 0.01 makes it difficult to achieve sufficient contrast against both light and dark backgrounds. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text. Using #0714ad for text or interactive elements would likely fail these criteria against most common background colors. To improve accessibility, it's crucial to use a lighter color for text or interactive elements placed on a #0714ad background, or to use #0714ad sparingly in designs intended for a broad audience. Tools for calculating contrast ratios can help designers choose appropriate color pairings.
