About International Klein Blue

International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. This specific shade of blue was developed as part of Klein's exploration of pure color and its ability to evoke emotional and spiritual responses. Klein aimed to capture the essence of the infinite, and IKB was central to this pursuit. The color's unique intensity is due to its high saturation and the matte finish of the paint Klein used, which enhances its visual impact. IKB is now a registered trademark. The intense shade of the blue is used in many creative fields.

International Klein Blue (#0022B4) presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it requires very light text (white or near-white) to ensure sufficient contrast for readability, meeting WCAG (Web Content Accessibility Guidelines) standards. Conversely, if used for text, a very light background is necessary. It's crucial to avoid pairing it with mid-tone colors, as this would likely result in insufficient contrast, making it difficult for users, especially those with visual impairments, to perceive the content effectively. Using color contrast checking tools during design and development is essential to ensure that the chosen color combinations meet accessibility requirements and provide an inclusive experience for all users.
