International Klein Blue
About International Klein Blue
International Klein Blue, represented by the hex code #0A23AA, is a deep, saturated blue pigment first developed by the French artist Yves Klein. Klein sought to create a blue that captured the essence of the sky and sea, embodying a sense of boundlessness and spirituality. The color is achieved through a specific formula involving a synthetic ultramarine pigment suspended in a clear resin binder. This unique combination enhances the color's intensity and luminosity. #0A23AA has since become iconic in the art world and is associated with creativity, innovation, and the exploration of the infinite. It is used in various applications, including painting, design, and fashion, to evoke a sense of depth and emotion.
The hex color #0A23AA, also known as International Klein Blue, presents some accessibility challenges, especially in web design. Its deep, saturated hue means that careful consideration must be given to text and interactive elements. When using #0A23AA as a background color, ensure that the foreground text has a sufficiently high contrast ratio, ideally meeting WCAG AA or AAA standards. Light shades of yellow, white, or light gray could provide adequate contrast. Avoid pairing #0A23AA with dark or similarly saturated colors, as this can reduce readability and cause eye strain. Additionally, consider providing alternative visual cues beyond color alone to convey information, such as using icons or text labels, to ensure that users with color vision deficiencies can still understand the content. Testing with accessibility tools and getting feedback from users with disabilities can help identify and address potential accessibility issues.

Applications
Web Design Accent
International Klein Blue, #0A23AA, can be used as a bold accent color in website design, particularly for calls to action or interactive elements. Its vibrancy draws attention and can create a memorable user experience. However, it should be used sparingly to avoid overwhelming the user. Combining it with neutral colors like white, light gray, or beige can balance its intensity and create a visually appealing design. In branding, #0A23AA can convey a sense of creativity, innovation, and sophistication, making it suitable for tech companies, art organizations, or educational institutions.
Interior and Fashion Accent
In interior design, #0A23AA can serve as a statement color for walls, furniture, or decorative accessories. A single accent wall painted in this hue can add depth and visual interest to a room. Pairing it with metallic accents like gold or silver can enhance its luxurious feel. In fashion, #0A23AA can be used in clothing or accessories to add a pop of color and create a bold, eye-catching look. A dress or a scarf in this color can make a stylish statement, especially when paired with neutral-colored outfits.
Data visualization
This intense blue may be used for data visualization. Blue shades are often the best choice for mapping quantitative variables (rainfall levels, population density). You can use this intense shade as the upper level. However, make sure that the values are displayed correctly and use a linear or exponential transformation if needed to have a smooth visual representation
