International Klein Blue

#0720AD

General Information about International Klein Blue

International Klein Blue (IKB), also known as #0720AD, is a deep blue hue that was developed by the French artist Yves Klein. Klein collaborated with a Parisian paint supplier to create a unique matte, ultramarine blue with the same color intensity and visual impact as dry pigment. The extraordinary vividness of IKB is the result of a synthetic resin binder that allows the pigment to maintain its brilliance and powdery appearance. Klein registered IKB as a trademark in 1957, solidifying its place in art history. This color is often associated with depth, transcendence, and the boundless nature of the imagination. Its striking and unique characteristics have made it a significant color for artistic and design endeavors.

The color #0720AD, a deep and intense blue, presents significant accessibility challenges, especially when used as a text color. Its low luminance value of 3 makes it difficult to achieve sufficient contrast against lighter backgrounds, potentially violating WCAG guidelines for color contrast ratios. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text or graphical elements. Using #0720AD for text requires careful consideration of background colors to ensure readability for users with visual impairments. To improve accessibility, consider pairing #0720AD with very light colors such as whites or very pale yellows. Alternatively, using it sparingly for decorative elements rather than crucial text could also mitigate accessibility issues. Testing with accessibility tools is crucial to confirm compliance.
