About International Klein Blue

International Klein Blue, represented by the hex code #041DBE, is a deep and intense 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 captured the essence of the sky and the sea, a color that would evoke feelings of infinity and spirituality. This particular blue is created with a synthetic ultramarine pigment. The color is known for its matte finish, which enhances its depth and intensity. In the RGB color model, it is composed of 1.6% red, 11.4% green, and 74.5% blue. In the CMYK color model, it consists of 98% cyan, 85% magenta, 0% yellow, and 25% black. International Klein Blue has been used extensively in art, fashion, and design to create a sense of depth, emotion, and sophistication.

The hex color #041DBE, also known as International Klein Blue, presents some accessibility challenges due to its low luminance. When used as a foreground color against a white background, the contrast ratio is insufficient to meet WCAG (Web Content Accessibility Guidelines) standards for normal text. This means that users with visual impairments may find it difficult to read text displayed in this color. To improve accessibility, consider using a lighter background color or a lighter shade of blue as the foreground. Alternatively, you could use a darker background color to increase the contrast ratio. When using this color for decorative purposes, ensure that it is not the sole means of conveying important information. Providing alternative cues, such as icons or text labels, can significantly improve accessibility for all users. Testing the color combination with accessibility tools is highly recommended to ensure compliance with accessibility standards. The use of this color should always be carefully evaluated within the context of the overall design to ensure it is not impairing the usability of the content.
