About International Klein Blue

International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein patented this color in 1957. What makes IKB unique is its intense vibrancy and visual impact, achieved through a specific formula that involves suspending pure ultramarine pigment in a synthetic resin. The resulting matte finish enhances the color's intensity, creating a captivating visual experience. This color is not just a shade of blue; it represents a specific artistic vision and intention. IKB has been used extensively in art, fashion, and design, becoming synonymous with modernity and sophistication. Its cultural significance is rooted in its artistic origins and the desire to capture a sense of infinite space and depth.

The hex color #0228b2, also known as International Klein Blue, presents significant accessibility challenges, especially in web design. Its dark hue results in very low contrast against light backgrounds, potentially making text or interactive elements illegible for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text to ensure readability. When using #0228b2 for text, a very light color like #FFFFFF (white) might be considered, but even then, careful evaluation is necessary to meet accessibility standards. For backgrounds, lighter tints or shades of blue or entirely different color palettes should be explored to enhance visibility and overall user experience. Tools like contrast checkers are essential to verify compliance with accessibility guidelines.
