International Klein Blue
About International Klein Blue
International Klein Blue (IKB), with the hexadecimal code #0B3BA9, is a deep shade of blue first mixed by the French artist Yves Klein. Klein registered this color as a trademark in 1957. What distinguishes IKB from other blues is its vivid intensity and high saturation. This is achieved by suspending pure color pigment in a clear synthetic resin, which allows the pigment to maintain its original qualities. The color is intended to evoke a feeling of immateriality and transcendence, reflecting Klein's artistic vision. IKB has found applications in diverse fields, including art, fashion, and design, where its striking appearance creates visual impact. Due to its unique spectral qualities, it tends to grab attention and stands for sophistication and creativity.
The color #0b3ba9, a deep shade of blue known as International Klein Blue (IKB), presents specific accessibility considerations for web developers. When used as a foreground color, it's essential to ensure sufficient contrast against background colors to meet WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Pairing IKB with light colors like white (#ffffff) or very light grays can help achieve this. Avoid using IKB for small text or essential UI elements without careful consideration of contrast. For users with visual impairments, including color blindness, relying solely on color to convey information is not advisable. Always provide alternative cues, such as text labels, icons, or patterns, to ensure content is accessible to everyone. Careful use of this vibrant color can enhance user experience without sacrificing accessibility.

Its boldness makes it suitable for highlighting key actions and promotions. In branding, the color helps to evoke a sense of trust and authority, without being dull and corporate as some other shades of blue. A website's design can become instantly recognizable and memorable with it.
Fashion Design
In fashion, IKB makes a statement. A dress or accessory in this color is sure to stand out. Due to its high pigment level, it's often seen in haute couture. The vibrancy lends itself to both casual and formal styles, making it a versatile choice for designers. However, it needs to be applied with care, as the strong appearance can be over the top.
Interior Design
In interior design, IKB can be used as an accent color to add a pop of vibrancy to a room. A single wall, a piece of furniture, or decorative elements in this color can create a focal point and inject personality into the space. Use in moderation, however, to prevent it from overwhelming the overall design, as it can make the room appear visually smaller.
