About International Klein Blue

International Klein Blue (IKB), represented by the hexadecimal color code #0320B1, is a deep, vivid shade of blue named after the French artist Yves Klein. Klein patented this particular shade of blue, which he used extensively in his artwork, particularly in his monochrome paintings. The color's intensity and purity are achieved through the addition of a synthetic ultramarine pigment to a polyvinyl acetate binder. IKB is known for its unique ability to evoke feelings of serenity, depth, and boundlessness. Its captivating quality has made it a popular choice in art, design, and fashion, appreciated for its striking visual impact and its association with creativity and innovation. The hex code #0320B1 signifies a color composed of very little red and green, with a high concentration of blue, resulting in its distinctive and recognizable appearance.

The hex color #0320B1, also known as International Klein Blue, presents significant accessibility challenges due to its very low luminance. When used as a foreground color on a white background, or vice versa, it fails to meet the contrast ratios recommended by WCAG (Web Content Accessibility Guidelines) for both normal text (4.5:1) and large text (3:1). This means that users with visual impairments, including those with low vision or color blindness, may struggle to read text or distinguish elements using this color. To improve accessibility, consider using a lighter shade of blue or pairing it with a much lighter color, such as a pale yellow or white, to ensure sufficient contrast. Alternatively, use #0320B1 for decorative elements where legibility is not critical.
