About International Klein Blue

International Klein Blue, often referred to as IKB, is a deep blue hue first mixed by the French artist Yves Klein. What makes this color unique is that Klein went to great lengths to patent and preserve the specific ultramarine pigment he used. Its intense saturation and matte finish give it a unique quality, making it stand out from other blues. IKB is achieved using a synthetic ultramarine pigment combined with a special resin suspension, which allows the color to maintain its brilliance and depth. Its distinctiveness has made it a popular color in art, fashion, and design.

The hex color #062fae, also known as International Klein Blue, presents some accessibility challenges, particularly regarding color contrast. When used as a foreground color for text, it requires careful consideration of the background color to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Given the darkness of #062fae, lighter background colors are necessary to meet these standards. White (#ffffff), light yellows, or very pale greens could potentially offer adequate contrast. It's crucial to test color combinations using accessibility tools to verify compliance. Also, avoid using this color as the sole indicator of interactive elements; supplement with text labels or other visual cues to improve accessibility for users with visual impairments.
