About International Klein Blue

International Klein Blue, represented by the hexadecimal color code #0724ad, is a deep, vivid blue hue renowned for its intensity and unique chromatic properties. It was specifically developed by the French artist Yves Klein in collaboration with a Parisian paint supplier. Klein sought to capture and preserve the pure, intense blue of the sky, aiming to evoke a sense of boundless space and spirituality. The color's unique formulation involves a synthetic ultramarine pigment suspended in a clear resin, which maintains the pigment's brilliance and allows it to retain its saturation. This striking blue has been prominently featured in Klein's monochrome paintings and sculptures, becoming a defining element of his artistic vision. Its cultural significance extends beyond the art world, influencing design, fashion, and various creative fields, symbolizing innovation and a sense of the infinite.

The hex color #0724ad, also known as International Klein Blue, presents several accessibility considerations for web developers. Its low luminance value (relative darkness) requires careful pairing with text and other interactive elements. To ensure readability and usability, it is imperative to use #0724ad with very light text colors, such as white or very pale shades of yellow or gray. The contrast ratio between text and background should meet WCAG (Web Content Accessibility Guidelines) standards, aiming for at least 4.5:1 for normal text and 3:1 for large text. Avoid using #0724ad for small text or essential interactive elements without sufficient contrast. In situations where precise color perception is crucial, alternative color schemes should be considered to accommodate users with color vision deficiencies. Moreover, always provide alternative cues (e.g., labels or icons) alongside color to convey information. Proper use of ARIA attributes can further enhance accessibility by offering descriptive information to assistive technologies.
