General Information about International Klein Blue

International Klein Blue, represented by the hexadecimal color code #0811AC, is a deep, vivid shade of blue renowned for its intense visual impact. It was specifically developed by the French artist Yves Klein in collaboration with a Parisian chemical company. Klein sought to capture the purest expression of blue, a color he believed embodied the infinite and the spiritual. The pigment's unique quality lies in its matte, ultramarine finish, achieved through a synthetic resin binder that suspends the color particles without dulling their intensity. This results in a color that appears to float on the surface, captivating the viewer with its depth and luminosity. This color is used to represent artistry.

The color #0811AC, also known as International Klein Blue, presents significant accessibility challenges, particularly concerning contrast. When used as a foreground color against a white or light background, it often fails to meet WCAG (Web Content Accessibility Guidelines) AA standards for color contrast, which require a contrast ratio of at least 4.5:1 for normal text. This means that users with low vision may struggle to read text displayed in this color. Similarly, when used as a background color, sufficient contrast with foreground text is crucial. To improve accessibility, consider pairing #0811AC with very light or white text, or darkening the color slightly to increase the contrast ratio. Tools such as contrast checkers can help evaluate and adjust color combinations to ensure they meet accessibility requirements, making content more usable for all users. It is important to consider that a color's appearance can vary slightly depending on the display device and ambient lighting, so testing on multiple devices is recommended.
