International Klein Blue
About International Klein Blue
International Klein Blue (IKB), with the hex code #0721ad, is a deep, vivid blue hue originally created and patented by the French artist Yves Klein. Klein sought to capture the purest expression of blue, believing it represented the cosmos, the infinite, and spiritual realms. The color achieves its unique intensity through the use of a synthetic ultramarine pigment mixed with a special matte resin suspension, which preserves the pigment's vibrancy. IKB has become iconic in art, design, and fashion, symbolizing depth, transcendence, and the immaterial. Its distinct appearance makes it instantly recognizable and has been used in various artistic and commercial contexts to evoke a sense of awe and contemplation. The color is visually impactful, and its use in design demands thoughtful consideration to its effect on the viewer or user.
The hex color #0721ad, also known as International Klein Blue (IKB), presents some accessibility challenges, especially in web design. Due to its deep, saturated nature and low lightness value, it offers poor contrast when paired with darker colors. As a general recommendation, use white (#ffffff) or very light grays as text or foreground colors to ensure sufficient contrast. When used as a background, consider using lighter shades of blues or complementary colors with high lightness values for foreground elements. Tools like contrast checkers can help determine if specific color combinations meet WCAG (Web Content Accessibility Guidelines) standards, aiming for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text to comply with AA level requirements. For AAA level compliance, these ratios increase to 7:1 and 4.5:1 respectively. Avoid using this color for critical information or interactive elements without careful consideration of contrast to ensure readability and usability for all users, including those with visual impairments.

Applications
Modern Art and Web Design
International Klein Blue is often used in modern art and design to create striking visual impacts. In web design, it can be used sparingly as an accent color to draw attention to specific elements, such as call-to-action buttons or headings, but should be combined with accessible color combinations to ensure a visually pleasing and inclusive user experience. Its boldness makes it suitable for branding where a sense of innovation and creativity is desired.
Fashion and Apparel
In the fashion industry, IKB can be used in bold statements, like a dress or accessory. It can also be incorporated into athletic wear, giving the wearer a sense of energy and dynamism. Because of its visual weight, it should be combined with more neutral tones to create a balanced outfit.
Interior Accents
While using IKB as a dominant color in interior design might be overwhelming, it can be used to add pops of color to a room. It works well as a statement wall in contrast to white or light grey walls. Use it in decorative pieces like vases, cushions or rugs. To ensure harmony and prevent the space from feeling too cold, complement it with warm accents and materials such as wood or metallics.
