About International Klein Blue

International Klein Blue, often referred to as IKB, is a deep blue hue first mixed by the French artist Yves Klein. It is renowned for its intensity and unique matte finish, achieved by suspending pure color pigment in a synthetic resin. Klein registered this color as a trademark in 1957, solidifying its place in art history. The color's captivating quality stems from its ability to evoke a sense of infinity and boundlessness, aligning with Klein's artistic exploration of the immaterial. IKB has since transcended the art world, finding applications in fashion, interior design, and various other creative fields. Its distinctive character continues to inspire and captivate designers and artists alike.

The color #0630AE, also known as International Klein Blue, presents significant accessibility challenges, particularly for users with visual impairments. Its dark hue against a dark background can result in poor contrast, making text and other visual elements difficult to discern. According to WCAG guidelines, sufficient contrast ratios are crucial for readability. For normal text (14 points) and larger text (18 points bold or larger), the contrast ratio should be at least 4.5:1 and 3:1, respectively, compared to the background. Using #0630AE as a foreground color requires careful selection of a background color to meet these standards. Light colors are recommended to improve the overall contrast and ensure a more accessible design. Testing with accessibility tools and user feedback is recommended to validate the effectiveness of color combinations.
