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 patented this color to maintain its uniqueness and association with his art. The color's intensity and depth arise from its high concentration of ultramarine pigment. In the RGB color model, #0022BB is composed of 0% red, 13.3% green, and 73.3% blue. Its captivating presence makes it a popular choice across different design disciplines, from fashion to graphic arts. It is a non-spectral color, meaning that it can not be created by light alone, and has to be created using pigments. The color is often associated with art, intelligence, stability, unity, and conservatism.
The color #0022BB, a deep shade of blue, presents considerable accessibility challenges. Its low luminance value results in poor contrast against light backgrounds, potentially making text and other visual elements difficult to read for users with visual impairments. According to WCAG guidelines, sufficient contrast is crucial for ensuring readability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Given the darkness of #0022BB, it is imperative to pair it with a very light color for text or interactive elements. Using tools to evaluate color contrast ratios is highly advisable during the design process. Additionally, relying solely on color to convey information should be avoided; instead, supplementary cues such as text labels or icons should be provided to enhance accessibility for all users, including those with color vision deficiencies.
