About International Klein Blue

International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. IKB's visual impact comes from its heavy reliance on ultramarine, as well as Klein's artistic use of this particular color. The color is a deep shade of blue tending towards violet, and the pigment's binder is polyvinyl acetate, which permits the pigment to maintain as much of its original qualities and color intensity as possible. Yves Klein registered this paint formula as a trademark under the name International Klein Blue (IKB) in 1957. It is regarded as one of the most important examples of a specific color's use and impact on the world of fine art.

The color #0422B0, a deep shade of blue also known as International Klein Blue, presents several accessibility considerations for web developers. Due to its high saturation and relatively low lightness, it offers limited contrast against typical background colors like white. This can pose challenges for users with visual impairments, making text or interactive elements difficult to read. It's crucial to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text, as recommended by WCAG guidelines. Using tools to check color contrast is essential. Additionally, avoid using this color as the sole indicator of interactive elements, as colorblind users may not be able to differentiate it. Providing alternative cues, such as underlines or icons, can improve accessibility for all users. Proper use of ARIA attributes can further enhance the experience for assistive technologies.
