About International Klein Blue

International Klein Blue (IKB), with the hex code #002EAD, is a deep blue hue first mixed by the French artist Yves Klein. Klein registered this color as a trademark in 1957. What sets IKB apart is its remarkable intensity and purity of color, achieved by suspending pure color pigment in a synthetic resin, allowing the pigment to retain its vibrancy. This color has become synonymous with Klein's artistic explorations, particularly his monochrome paintings. It is designed to create the greatest possible impact, it is more than just a color. It is a symbol for modern art. This particular shade of blue sits distinctly between cyan and a deeper ultramarine, embodying both depth and energy, and it holds a unique place in the history of art and design.

The color #002EAD, also known as International Klein Blue (IKB), presents significant accessibility challenges, especially in web design. Its dark hue results in very low contrast when paired with standard light text colors like white or light gray, potentially failing WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. To ensure inclusivity, it's crucial to use IKB sparingly and thoughtfully. When employing this color for text or interactive elements, it's imperative to select a highly contrasting color for the background or foreground, respectively. A lighter shade of yellow or a very pale off-white would be more appropriate choices. Testing the color combination with accessibility tools is highly advisable to verify compliance with accessibility standards, ensuring that content remains perceivable and usable for individuals with visual impairments. Employing strategies such as incorporating larger font sizes or adding subtle text shadows can also improve readability and overall accessibility. Be aware of color blindness and choose combinations tested for this.
