General Information about International Klein Blue

International Klein Blue (IKB), with the hex code #051AAE, is a deep and vivid shade of blue that is strongly associated with the French artist Yves Klein. Klein registered this color as a trademark in France, seeking to preserve its unique identity. It is characterized by its intense saturation and almost ultramarine quality. The color is achieved through a specific formulation that includes a synthetic ultramarine pigment. Due to its distinctive appearance, IKB has become a symbol of modern art and has been widely adopted in various fields, including fashion, design, and architecture. Its vibrancy and depth make it a visually striking color that demands attention.

International Klein Blue, represented by the hex code #051AAE, presents several accessibility considerations for web developers. Its dark hue offers good contrast against white or very light backgrounds, generally meeting WCAG standards for text legibility. However, when used with dark backgrounds, ensuring sufficient contrast is paramount. Tools like contrast checkers are invaluable in verifying compliance with WCAG AA or AAA levels. In user interface design, avoid using this color as the sole indicator of interactive elements, such as links or buttons, as colorblind users may not perceive the distinction. Instead, supplement it with other visual cues like underlines, borders, or icons. When paired with other colors, careful consideration should be given to potential colorblindness perception. Simulators can help designers preview how color combinations will appear to individuals with different types of color vision deficiency. Remember to conduct thorough accessibility testing with diverse users to ensure inclusivity and optimal user experience.
