General Information about International Klein Blue

International Klein Blue, represented by the hex code #0029C6, is a deep ultramarine blue hue known for its intensity and brilliance. It was developed by the French artist Yves Klein in collaboration with a Parisian paint dealer, Edouard Adam, to capture the purest expression of blue. Klein registered this color under the name International Klein Blue (IKB) in 1957. The color's unique quality comes from its matte, highly saturated finish, which enhances its visual impact. This specific shade of blue has become iconic in art, design, and fashion, representing creativity, transcendence, and the infinite. The color is a popular choice for artists and designers who want to make a bold statement. Its unique properties make it stand out.

The hex color #0029c6, a deep and vibrant blue reminiscent of International Klein Blue, presents specific accessibility considerations for web developers. When used as a background color, it is crucial to ensure sufficient contrast with the foreground text. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Lighter shades of yellow, white, or gray are often suitable choices for foreground text to meet these contrast requirements. Using a color contrast checker tool can help verify compliance. Additionally, avoid relying solely on color to convey important information, as users with color vision deficiencies may not be able to distinguish it. Providing alternative cues, such as text labels or icons, can enhance accessibility for all users. When used for interactive elements, ensure a clear visual focus indicator is present for keyboard navigation.
