International Klein Blue

General Information about International Klein Blue

International Klein Blue, also known as IKB, is a deep blue hue mixed by Yves Klein. The vividness of IKB is thanks to its heavy presence of ultramarine, creating an impression of something beyond our physical presence. It is often associated with depth, stability, and confidence. In color psychology, blue is known to promote feelings of calmness and serenity, while also symbolizing trust and intelligence. IKB's high saturation makes it stand out and command attention, which is why it's often used in artistic and design contexts where making a bold statement is desired. The color is registered as a trademark under Yves Klein's name.

The hex color #0126c9, also known as International Klein Blue, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value of 4.22 makes it difficult to achieve sufficient contrast against common background colors like white. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using #0126c9 for text on a white background would likely fail these contrast tests, making it hard for users to read. To improve accessibility, consider using lighter shades of blue or pairing it with a darker background color to enhance contrast. Additionally, avoid relying solely on color to convey important information; use text labels or icons to ensure inclusivity. Proper color contrast is not only vital for users with visual impairments but also benefits all users by improving readability and reducing eye strain. Testing with accessibility tools is crucial before deploying this color in web design.
