International Klein Blue
About International Klein Blue
International Klein Blue, often abbreviated as IKB, is a deep blue hue remarkable for its intensity. Specifically, it is a vivid, ultramarine blue. The color was developed by the French artist Yves Klein in collaboration with a Parisian paint dealer, Edouard Adam, to capture and maintain the intensity and brilliance of pure ultramarine pigment. Klein registered IKB as a trademark in 1957. The visual impact of IKB comes from its reliance on pure pigment, which, when suspended in a synthetic resin, retains its luminosity and depth. This color has become synonymous with Klein's art and is prominently featured in his monochrome paintings and sculptures. Beyond art, IKB has been adopted in various fields, including fashion, interior design, and branding, owing to its striking and memorable aesthetic.
International Klein Blue, represented by the hex code #0B31B2, presents distinct accessibility considerations for web developers. Its deep, saturated hue results in low luminance, meaning that text or interactive elements using this color as a background require careful attention to contrast ratios. According to WCAG guidelines, sufficient contrast between foreground and background colors is essential for readability and usability, particularly for users with visual impairments. To ensure accessibility, developers should pair #0B31B2 with light-colored text, such as white or very pale yellow. Tools that assess color contrast ratios can help determine if the chosen combination meets the minimum requirements for different levels of compliance. Avoid using this color for small text or intricate icons, as the low contrast may make them difficult to discern. Implementing these strategies will enhance the inclusive design of websites and applications, making them accessible to a wider range of users.

Web Design and UI/UX
International Klein Blue can serve as a bold background color for website headers or call-to-action buttons, drawing the user's eye and creating a sense of depth and sophistication. Its intense hue is well-suited for designs aiming to convey innovation and creativity. In UI design, consider using it sparingly to highlight key interactive elements, as overuse can be visually overwhelming. Combining it with white or light gray elements can create a clean and modern aesthetic. For branding, International Klein Blue can be used to establish a memorable and distinctive identity, particularly for technology companies, art institutions, or luxury brands.
Beauty and Fashion
This color is highly regarded in the beauty sector, particularly for eye makeup. The color creates a statement look when used as an eyeshadow or eyeliner. The hue accentuates different eye colors and can provide a great, daring contrast. In fashion, use as a stand out color for garments.
Interior Design
In interior design, International Klein Blue can be used to create a statement wall in a living room or bedroom, adding a touch of drama and sophistication. It works well as an accent color, particularly when paired with neutral tones such as white, gray, or beige.

The intense blue hue can evoke a sense of calm and tranquility, making it suitable for spaces intended for relaxation and contemplation. Use the hue in moderation to prevent the room from feeling overwhelming.
