International Klein Blue
About International Klein Blue
International Klein Blue (IKB), also known as #0622C4, is a deep blue hue first mixed by the French artist Yves Klein. IKB's visual impact comes from its heavy reliance on ultramarine pigment, as well as Klein's matte, synthetic resin binder, which allows the pigment to maintain its brilliance when dry. Klein registered IKB as a trademark in 1957, although its not technically a color that can be trademarked. Its unique, saturated quality is often associated with feelings of depth and infinity. In the RGB color model, it is composed of 2.4% red, 13.33% green, and 76.86% blue. In the CMYK color model, it is composed of 97% cyan, 83% magenta, 0% yellow, and 23% black. Its an uncommon and striking color choice.
The color #0622C4, or International Klein Blue, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value of approximately 2.5% relative to white means that text rendered in this color on a white background, or vice versa, will likely fail WCAG (Web Content Accessibility Guidelines) AA and AAA standards for contrast ratio. These standards require contrast ratios of 4.5:1 and 7:1 respectively for normal text and 3:1 for large text. Due to its deep hue, sufficient contrast can only be achieved by pairing it with very light colors such as white or very pale yellows. When using International Klein Blue, it's crucial to provide alternative styling options that offer higher contrast for users with low vision or color blindness. Tools like contrast checkers should be employed during design to ensure accessibility compliance and a better user experience. It is generally advisable to avoid using this color for critical text or interactive elements without careful consideration of contrast and alternative styling.

Applications
Modern Art Installations
International Klein Blue is often used in modern art installations to create visually striking and immersive environments. Its intense saturation evokes feelings of depth and boundlessness. This color can be applied to large canvases or used as a backdrop for sculptures to enhance their visual impact and create a unique sensory experience. The color's ability to absorb light also makes it suitable for creating a sense of infinity and transcendence in artistic spaces. Klein believed the color had a quality close to pure space and wished to associate it with immateriality, which makes it a great choice for abstract art.
Web Design Accents
In web design, International Klein Blue can be used strategically to draw attention to key elements or create a bold, modern aesthetic. It's particularly effective as an accent color in user interfaces, where it can be used for buttons, links, or highlights. However, due to its low luminance, it is crucial to use it sparingly and ensure adequate contrast with surrounding elements. Using it as a background color should be done with caution and careful consideration of text readability. Generally, it should be paired with light text. It can also be a good choice for data visualization.
