About International Klein Blue

International Klein Blue, represented by the hexadecimal color code #0711AD, is a deep, vibrant shade of blue known for its intensity and artistic significance. It was created by the French artist Yves Klein and patented in 1957. Klein chose this particular shade of blue because he believed it best conveyed the feeling of boundlessness and spirituality he sought to express in his art. The color is a very dark shade of blue. The pigment's unique composition and matte finish contribute to its striking visual impact. The color is rarely seen outside of artistic circles and it is rarely seen in web applications because of its accessibility issues. The color has a strong psychological impact and may evoke feelings of calmness, creativity, and introspection.

The color #0711AD, also known as International Klein Blue, presents significant accessibility challenges. Its extremely dark hue results in very low contrast against light backgrounds, potentially causing readability issues for users with visual impairments. According to WCAG guidelines, sufficient contrast is crucial for text and interactive elements. Using #0711AD for text on a white background, for instance, would likely fail contrast ratio requirements. To improve accessibility, it is highly recommended to pair this color with very light shades, ideally near-white, or implement alternative color schemes that provide a higher contrast ratio. Tools like contrast checkers can help determine appropriate color combinations that meet accessibility standards, ensuring a more inclusive user experience. Furthermore, avoid using #0711AD as the sole indicator for interactive elements; supplement it with additional cues like underlines or icons.
