International Klein Blue
About International Klein Blue
International Klein Blue (IKB), with the hex code #0227C8, is a deep ultramarine blue hue first mixed by the French artist Yves Klein. Klein registered this color as a trademark in 1957. The visual impact of IKB comes from its heavy reliance on ultramarine pigment, combined with a matte, synthetic resin binder that suspends the pigment and allows the color to achieve maximum luminosity. Because of its stunning quality, IKB became iconic and synonymous with Klein's artistic exploration of immateriality and the infinite. This color is often associated with creativity, depth, and a sense of the sublime, and has found use in various artistic and design applications.
The hex color #0227c8, also known as International Klein Blue, presents considerable accessibility challenges, primarily due to its very low luminance. Its stark contrast against white backgrounds can cause eye strain for some viewers, and it will fail WCAG (Web Content Accessibility Guidelines) contrast ratio requirements for standard-sized text. When using this color for text or interactive elements, ensure a high contrast ratio (at least 4.5:1 for normal text and 3:1 for large text) against the background. Consider pairing it with light or desaturated hues for improved readability. Avoid using it for essential information if possible or use enhanced text sizes. Proper testing with accessibility evaluation tools and diverse user groups is crucial to ensure inclusivity for users with visual impairments. It is more suited as an accent color.

Applications
Website Accent Color
International Klein Blue adds a bold and artistic flair. It can be used to highlight key features or navigation elements. However, it should be implemented sparingly as an accent to avoid overwhelming the user. Use it for decorative shapes to create visual interest without impacting content legibility. It is suitable for websites related to art, technology, or innovation, where a strong, modern aesthetic is desired. Always prioritize usability by ensuring sufficient contrast with text and other interactive components.
Interior Design Accent
In interior design, International Klein Blue can introduce a striking focal point within a space. Consider using it as a wall color in a room with ample natural light, or incorporating it as a statement piece through furniture or artwork. It pairs well with neutral tones like white, gray, and beige to create a balanced and sophisticated look. The use of this blue should be handled thoughtfully to prevent the space from feeling too dark or overwhelming. When accessorizing, complementary colors can further enhance the space.
Fashion Design
This iconic color has been used in fashion design for decades, often appearing in statement pieces and accessories. Its intense, ultramarine hue adds a touch of boldness and creativity. Think of incorporating it into a dress, blazer, or even shoes to make a memorable statement. Because of its intensity, this color is best paired with neutrals such as black, white or gray. For those who prefer bold color combinations, consider matching the blue with vibrant orange or yellow accessories.
