About International Klein Blue

International Klein Blue, represented by the hexadecimal color code #0124B3, is a deep, saturated blue hue known for its intensity and vibrancy. It was originally created by the French artist Yves Klein, who sought to capture the purest expression of blue. Klein patented the color in 1957 to preserve its unique quality. IKB, as it's also known, is characterized by its ultramarine pigment, suspended in a synthetic resin, which allows the color to retain its luminosity and depth. The color evokes feelings of infinity, spirituality, and boundlessness. It is frequently used in art, design, and fashion to create a sense of drama and visual impact. In digital color spaces, it is made up of 0.4% red, 14.1% green and 70.2% blue.

The hex color #0124B3, a deep and vibrant blue, presents some accessibility challenges, especially in text applications. When used as a foreground color, it requires careful consideration of contrast ratios against background colors. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Given its low lightness value, #0124B3 necessitates a very light background color to meet these standards. White (#FFFFFF) or very pale shades of yellow or green could potentially provide sufficient contrast. However, it's crucial to test the color combination with accessibility tools to ensure compliance. Avoid pairing #0124B3 with dark or similarly saturated colors, as this will likely result in insufficient contrast and readability issues for users with visual impairments. For decorative elements or large graphical areas, the contrast requirements are less stringent, allowing for greater flexibility in color choices.
