International Klein Blue
About International Klein Blue
International Klein Blue, often referred to as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein registered this color as a trademark in 1957. What makes IKB unique is its ultramarine pigment's high concentration combined with a synthetic resin binder that allows the pigment to maintain its brilliance and intensity. The visual impact of IKB comes from its almost complete lack of reflectance. Klein used IKB in his monochrome paintings, sculptures, and even performances. This color is intended to evoke a sense of boundlessness and spirituality. It continues to be influential in art, design, and fashion to this day, symbolizing innovation and creativity.
The hex color #072EB1, also known as International Klein Blue, presents significant accessibility challenges, especially for users with visual impairments. Its low luminance value (approximately 4.3) results in poor contrast against white backgrounds, making text and interface elements difficult to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. #072EB1 falls far short of these recommendations. To improve accessibility, consider pairing it with much lighter colors or using it sparingly for decorative purposes. Providing sufficient contrast ensures that content is perceivable by a wider audience, including individuals with low vision or color blindness. Adequate spacing and clear typography can further enhance readability when using this deep blue hue. Also, avoid using it as a sole indicator, like in graphs or charts.
