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 sought to create a blue that captured the essence of the sky and the sea, and he registered this particular shade as a trademark in 1957. The color's intensity and unique ultramarine tone are achieved through a specific pigment, allowing for an unparalleled sense of depth and luminosity. IKB is a pure, unbound color, which Klein viewed as representative of the infinite and immaterial aspects of existence. The use of a synthetic resin binder helped maintain the color's brilliance without dulling it, making it stand out. This innovative use of color revolutionized art, inspiring artists and designers to explore the emotional and spiritual qualities of color.

The color #092EAB, also known as International Klein Blue, presents some accessibility challenges, especially when used as a background color for text. Due to its dark hue and strong saturation, sufficient contrast is crucial to ensure readability for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #092EAB for text or interactive elements, it's important to pair it with a light color like white (#FFFFFF) or a pale yellow to meet these contrast requirements. Tools are available online to check color contrast ratios. Furthermore, it is important to consider users with color vision deficiencies and avoid using color alone to convey important information. Supplementary cues, such as text labels or icons, are essential for universal usability. Proper testing with accessibility tools is highly recommended to ensure an inclusive design.
