About International Klein Blue

International Klein Blue, represented by the hex code #0A2FAA, is a deep and intense shade of blue. It was originally created by the French artist Yves Klein in collaboration with a Parisian paint dealer, Edouard Adam, to capture the luminous quality of ultramarine pigment. Klein registered this color as a trademark, solidifying its unique identity in the art world. The color is known for its strong visual impact and has been widely adopted in various fields beyond art, including fashion, design, and technology. The creation of this color marked an iconic moment in art history. It represents the artist's dedication to color and its emotional power.

The color #0A2FAA, also known as International Klein Blue, presents some accessibility challenges, particularly regarding color contrast. When used as text against a white background, it may not meet the WCAG (Web Content Accessibility Guidelines) standards for sufficient contrast ratio. This is crucial for users with visual impairments. To improve accessibility, consider using a lighter background or a lighter text color. Tools like contrast checkers can help determine if the color combination meets accessibility standards. Providing alternative visual cues, such as icons or text decorations, can further enhance usability for all users, especially those with color blindness. Moreover, ensure that interactive elements using this color have clear focus indicators for keyboard navigation.
