About International Klein Blue

International Klein Blue, represented by the hex code #0c39a8, is a deep, vibrant shade of blue that lies within the blue-violet spectrum. This color is famous for its matte appearance and strong visual impact. It was developed by the French artist Yves Klein, who patented the color in 1957 to ensure its unique quality was maintained. He sought a blue that conveyed a sense of depth and boundlessness, evocative of the sky and the sea. The color has become a symbol of modern art and is often associated with creativity, innovation, and a sense of the infinite. Its rich hue has found applications in art, fashion, design, and technology, often evoking feelings of inspiration and introspection.

The hex color #0c39a8, also known as International Klein Blue, presents certain accessibility challenges, particularly in text-based applications. Its dark hue necessitates careful consideration of color contrast ratios to ensure readability for individuals with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #0c39a8 as a background color, it is crucial to pair it with a light foreground color, such as white or a very light shade of yellow, to meet these contrast requirements. Tools like contrast checkers can be invaluable in verifying compliance. Additionally, avoid relying solely on color to convey important information, as colorblind users may not be able to distinguish it. Providing alternative cues, such as text labels or icons, is essential for ensuring inclusivity.
