About International Klein Blue

International Klein Blue (IKB), hex code #0722AD, is a deep shade of blue first mixed by the French artist Yves Klein. Klein patented IKB in 1957 to maintain the color's fidelity in his art. The color is renowned for its intense saturation and velvety appearance. It is achieved by suspending pure color pigment in a clear synthetic resin, which allows the pigment to retain its brilliance. IKB has become an iconic color, often associated with modern art, innovation, and a sense of the infinite. Its unique hue has been used extensively in fashion, design, and technology to evoke a sense of sophistication and creativity. The distinct properties of IKB make it a captivating color that continues to inspire artists and designers worldwide.

The hex color #0722AD, also known as International Klein Blue, presents several accessibility considerations for web development. Given its dark hue, it's crucial to ensure sufficient contrast when used as a background or text color. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Pairing this dark blue with light colors like white (#FFFFFF) or very light yellows can achieve adequate contrast. However, using it with similar dark tones could render content illegible for users with visual impairments. Careful attention to color combinations and the use of tools to evaluate contrast ratios are essential for creating an inclusive and accessible web experience. Additionally, providing alternative cues beyond color, such as text labels or icons, can further enhance accessibility for users with color blindness.
