About International Klein Blue

International Klein Blue (IKB), represented by the hexadecimal color code #0528af, is a deep, vivid blue hue originally created by the French artist Yves Klein. It's renowned for its remarkable intensity and purity, achieved through a specific pigment formulation that maximizes the color's visual impact. Klein registered IKB as a trademark in 1957, solidifying its unique place in art history. The color is frequently associated with feelings of depth, infinity, and transcendence. IKB's intense saturation makes it stand out, drawing the viewer's eye and creating a memorable visual experience. Its popularity extends beyond the art world, influencing graphic design, fashion, and interior design due to its striking appearance and evocative qualities.

The hex color #0528af, also known as International Klein Blue, presents some accessibility challenges, especially concerning color contrast. When used as a foreground color for text, it requires careful consideration of the background color. According to WCAG guidelines, sufficient contrast is crucial for readability, particularly for users with visual impairments. Using a very light color like #FFFFFF for the background would create a contrast ratio of approximately 15.6:1, which is excellent and easily passes the WCAG AA and AAA standards for text and non-text contrast. However, when paired with darker backgrounds, such as shades of gray or black, the contrast ratio may fall below the recommended levels, making the text difficult to read. Therefore, it's essential to use a color contrast checker to ensure compliance with accessibility standards, ensuring that the text remains legible for all users. For non-text elements, ensure a contrast ratio of at least 3:1.
