About International Klein Blue

International Klein Blue, with the hexadecimal code #091FAB, is a deep, intense shade of blue. It is named after the French artist Yves Klein, who registered the color as a trademark in 1957. Klein sought to capture the purest expression of blue, believing it to convey a sense of infinity and spirituality. The color is created using a synthetic ultramarine pigment, which gives it its characteristic vibrancy and depth. This particular shade of blue has been widely used in art, fashion, and design to evoke feelings of awe and wonder. Its unique intensity makes it stand out from other blues, capturing the viewer's attention and sparking their imagination. International Klein Blue is celebrated for its ability to create a strong visual impact and convey a sense of the sublime.

The color #091FAB, also known as International Klein Blue, presents some accessibility challenges. With a low luminance, it can be difficult to read text against a background of this color, especially for users with visual impairments. The contrast ratio against white is quite low, failing WCAG standards for both normal and large text. To improve accessibility, consider using a lighter background color to increase contrast. Another option is to use a larger font size or a bolder font weight to make the text more readable. For crucial elements, such as buttons or links, providing clear visual cues beyond color alone is essential. Adding an underline to links or a distinctive border to buttons can aid users who have difficulty distinguishing colors. Also, avoid using this color as the sole means of conveying important information. Always pair it with text or icons to ensure that the content is accessible to everyone.
