International Klein Blue
About International Klein Blue
International Klein Blue (IKB), with the hexadecimal color code #0313B1, is a deep, intense blue pigment first synthesized in 1956 by the French artist Yves Klein. Klein sought to create a blue that was as pure and vivid as possible, evoking a sense of boundlessness and spiritual depth. The color was officially patented as International Klein Blue in 1957. The pigment's unique matte finish further enhances its intensity, making it appear almost otherworldly. It is achieved by suspending pure ultramarine pigment in a synthetic resin, which allows the pigment to retain its luminosity. The color's striking appearance has made it a favorite in art, fashion, and design.
The hex color #0313B1, also known as International Klein Blue, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance of 0.007 makes it difficult to perceive against both light and dark backgrounds. According to WCAG guidelines, it fails all contrast ratio tests against white (#FFFFFF) and black (#000000). To ensure accessibility, avoid using this color for text or interactive elements. If it is imperative to use this color, ensure that adjacent colors provide a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Consider using a color contrast checker tool to verify compliance. Furthermore, avoid relying solely on color to convey information, as users with color vision deficiencies may not be able to distinguish it from other colors. Providing alternative cues, such as text labels or icons, is crucial for inclusive design.
