About International Klein Blue
International Klein Blue (IKB), with the hex code #0218A7, is a deep blue hue first synthesized and trademarked by the French artist Yves Klein. This color is renowned for its intense and captivating visual impact, achieved through a specific ultramarine pigment. Klein registered this color in 1957 to preserve its unique quality and impact. It's a saturated and non-reflective blue, which gives it a unique visual presence. IKB has since been adopted in various fields, including art, fashion, and design, where its striking appearance continues to make it a popular choice. The color is often associated with concepts of openness, spirituality, and infinity.
The hex color #0218A7, also known as International Klein Blue, presents significant accessibility challenges due to its very low luminance. When used as a foreground color, it requires a very light background to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratio. Text using this color on a white background fails WCAG AA and AAA standards. To ensure readability and usability, particularly for users with visual impairments, it is crucial to pair this color with much lighter shades. Adequate contrast is essential for conveying information effectively and providing a positive user experience. Tools for checking color contrast ratios should be used during the design process. Considering alternatives or modifications to the color may be necessary in some cases to improve accessibility while retaining the intended aesthetic.

Applications
Web Design Accent
In web design, International Klein Blue can be employed as an accent color to draw attention to specific elements, such as buttons or links. Due to its intensity, it should be used sparingly and strategically to avoid overwhelming the user. It can also be used for backgrounds of call-to-action sections if sufficient contrast is provided with the text. This creates a bold statement and adds a touch of sophistication. However, caution is advised to ensure that accessibility guidelines are met by pairing it with appropriate complementary colors, especially for text and interactive elements, ensuring a positive user experience.

The intense color is perfect for creating memorable looks. The color is used in dresses, suits, or even accessories like scarves and handbags. Given its vibrant nature, Klein Blue works best when balanced with neutral colors or used as a focal point in an outfit.
