About International Klein Blue

International Klein Blue, with the hex code #041DB0, is a deep, vibrant shade of blue that is strongly associated with the French artist Yves Klein. Klein patented this particular shade of blue, which he used extensively in his artwork, especially in his monochrome paintings. The color is notable for its intense saturation and depth, creating a visually striking effect. It is created by suspending pure color pigment in a clear synthetic resin, which maintains the pigment's original qualities. The unique matte finish contributes to its intensity and allure. Due to its bold nature, it is often used to evoke feelings of depth, creativity, and infinity. In digital contexts, the color can be difficult to reproduce exactly, but efforts are made to match its distinctive appearance.

The hex color #041DB0, also known as International Klein Blue, presents significant accessibility challenges due to its low luminance. When used as text, it requires a very light background to ensure sufficient contrast for readability, adhering to WCAG guidelines for color contrast ratios. A dark color like this can be problematic for users with visual impairments. To mitigate these issues, consider pairing it with colors that offer a high contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Also, avoid using this color to convey important information without additional cues, such as icons or text labels, to accommodate users who may have difficulty distinguishing it from the background. Ensure that interactive elements using #041DB0 have clear visual indicators to aid usability for all users, including those with cognitive disabilities.
