About International Klein Blue
International Klein Blue, often referred to as IKB, is a deep blue hue first mixed by the French artist Yves Klein. It is renowned for its intense saturation and visual impact. Klein specifically chose this particular shade of ultramarine because of its perceived capacity to convey pure ideas and evoke a sense of boundless space. Chemically, IKB is achieved through a specific formulation that preserves the pigment's original intensity by suspending it in a synthetic resin that allows the pigment to maintain its brilliance. This color holds a unique place in art history and continues to inspire artists and designers across various creative fields. Its captivating depth and distinctive character make it a standout choice for projects seeking to evoke emotion and captivate audiences.
The hex color #073BA7, also known as International Klein Blue, presents significant accessibility challenges, especially for users with visual impairments. Its low luminance value of 4.5 cd/m² means that text rendered in white on this background barely meets the WCAG 2.0 Level AA contrast ratio threshold of 4.5:1 for normal text, making it difficult to read for some users. For larger text (18pt or 14pt bold), it just passes this requirement. To ensure accessibility, it's crucial to use lighter text colors or implement adjustments to increase contrast. When combined with dark text, the contrast ratio is extremely low. Designers should thoroughly test color combinations with tools like the WebAIM Contrast Checker. Consider alternatives like slightly lightened shades of blue or complementary colors to enhance readability and inclusivity for all users, paying close attention to the needs of users with color vision deficiencies.

Applications
UI Design
International Klein Blue (IKB) is a distinctive deep blue hue often associated with Yves Klein's art. In web design, its bold character can draw attention to call-to-action buttons or highlight key information sections. However, given its low luminance, IKB should be used sparingly to prevent eye strain and maintain accessibility standards. When employing IKB in a user interface, ensure that any text or interactive elements placed on top of it have sufficient contrast. Complementary colors or carefully chosen tints and shades can also create visual interest while preserving legibility.
Fashion Design
In fashion, International Klein Blue makes a statement. The bold and saturated hue draws the eye, making it suitable for accent pieces such as scarves, handbags, or shoes. The color is a strong choice for statement pieces like cocktail dresses or formal wear. When incorporating IKB into an outfit, consider balancing it with neutral colors like white, black, or gray to create a harmonious overall look. The vibrant nature of IKB makes it a memorable and eye-catching color choice for fashion designers looking to add a pop of color to their collections.
Interior Design
International Klein Blue can add a touch of sophistication and artistic flair to interior spaces. Use the color to create an accent wall in a living room or bedroom, or select furniture pieces like chairs or sofas in this striking shade. When using IKB in interior design, balance it with softer, neutral tones to prevent the space from feeling overwhelming. Incorporate natural materials like wood and textiles to add warmth and texture. Consider using IKB in art pieces or decorative objects to create focal points and add visual interest.
