International Klein Blue
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. The color's remarkable intensity and purity stem from its reliance on ultramarine pigment, a synthetic version of lapis lazuli. Klein considered this particular shade of blue to possess unique qualities, representing the cosmos and boundless space. He used IKB extensively in his monochrome paintings and sculptures, seeking to evoke a sense of transcendence and spiritual experience. The color has since become iconic in the art world, admired for its captivating depth and historical significance.
The hex color #0525c5, also known as International Klein Blue, presents significant accessibility challenges, especially in web design. Its very low luminance value (approximately 0.01) means that text rendered in this color on a white background, or vice versa, will likely fail WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. These guidelines mandate a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text to ensure readability for users with visual impairments. Therefore, when using this color, it is crucial to pair it with a very light color for text, such as white (#ffffff), and even then, it should be tested rigorously to ensure it meets accessibility standards. Alternatively, consider using this color sparingly, perhaps for graphical elements rather than essential text, or use a darker shade with a higher luminance when text needs to be displayed. The use of accessibility evaluation tools is highly recommended.
