General Information about International Klein Blue

International Klein Blue, represented by the hexadecimal color code #0324B1, is a deep and highly saturated shade of blue. It is named after the French artist Yves Klein, who patented the color in 1957. Klein sought to create a blue that was as pure and intense as possible, believing that it could convey a sense of boundless space and spiritual depth. This color is achieved through the use of a specific ultramarine pigment. In the RGB color model, #0324B1 is composed of 1.18% red, 14.12% green, and 69.41% blue. In the CMYK color model, it consists of 99% cyan, 80% magenta, 0% yellow, and 31% black. This blue is often associated with creativity, intelligence, and spirituality. In practical applications, it can make a design or product stand out because of its high saturation and unusual appearance.

The hex color #0324B1, also known as International Klein Blue, presents several accessibility considerations for web developers. Its extremely dark hue results in very low contrast when paired with similarly dark colors, making text and interactive elements nearly illegible for all users. To ensure accessibility, it's crucial to use #0324B1 exclusively with very light colors, ideally white (#FFFFFF) or very light shades of gray, to achieve a contrast ratio that meets WCAG (Web Content Accessibility Guidelines) standards. Using online contrast checkers is highly recommended to verify sufficient contrast. This color is not suitable for conveying crucial information if color is the only differentiating factor. Developers should also provide alternative cues, such as text labels or icons, to ensure content is accessible to users with visual impairments, including those with color blindness. If this hex color is used as a background, ensure interactive elements have clear focus states. Careful consideration is crucial for creating an inclusive experience.
