About International Klein Blue

International Klein Blue, also known as IKB, is a deep blue hue first mixed by the French artist Yves Klein. This specific shade of blue was synthetically created and registered as a trademark by Klein. Its intense and ultramarine nature is due to Klein's desire to achieve the purest expression of blue, believing it conveyed a sense of limitless space and spirituality. Chemically, the color is a deep shade of ultramarine, achieved through a specific mixture of pigments and a synthetic resin binder. IKB gained recognition for its use in Klein's monochrome paintings and sculptures, which sought to evoke a transcendental experience for the viewer. The color is often associated with modern art and continues to inspire artists and designers across various fields due to its unique vibrancy and depth.

The hex color #061EAE, also known as International Klein Blue, presents significant accessibility challenges, especially in web design. Its dark hue results in very low contrast against standard light backgrounds, potentially violating WCAG (Web Content Accessibility Guidelines) standards. To ensure readability and usability for all users, including those with visual impairments, it's crucial to use this color with very light foreground text or interface elements. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. Careful consideration should also be given to the size and weight of the text displayed against this background. For interactive elements like buttons or links, sufficient contrast is essential to ensure that users can easily identify and interact with them. Testing with accessibility tools is highly advised to confirm that the color combination meets accessibility requirements. Using a lighter shade of blue or a different color entirely might be a better solution for optimal accessibility.
