General Information about International Klein Blue

International Klein Blue, represented by the hex code #0D1DBD, is a deep, vivid blue color named after the French artist Yves Klein, who patented the unique formulation of this hue. It's renowned for its intense saturation and captivating visual impact. Chemically, it's achieved by suspending ultramarine pigment in a synthetic resin, which enhances the color's brilliance. The color is not just a simple mixture of RGB values; it has a cultural significance tied to art history and innovation. In the RGB color model, #0D1DBD is composed of 5.1% red, 10.6% green, and 74.1% blue. It's often associated with creativity, depth, and a sense of the infinite. Because of its cultural associations with art, this color has a powerful impact on any product or marketing material.

The hex color #0D1DBD, also known as International Klein Blue, presents some accessibility challenges for web developers. Its dark hue results in a low contrast ratio when paired with lighter text colors, potentially making it difficult for users with visual impairments to read. According to WCAG guidelines, sufficient contrast is crucial for ensuring readability. To improve accessibility, consider using a very light text color such as white (#FFFFFF) or a very light grey. It's vital to test color combinations using accessibility tools to ensure compliance with WCAG standards, enhancing the user experience for everyone. Furthermore, providing alternative text descriptions for images and interactive elements can supplement color-based information, making the content more accessible to users who rely on screen readers or have difficulty distinguishing colors. Remember that accessible design benefits all users, not just those with disabilities.
