About International Klein Blue

International Klein Blue, also known as IKB, is a deep shade of blue first mixed by the French artist Yves Klein. Klein sought to develop a blue that most represented his concept of pure blue art, which he associated with immateriality and infinity. IKB's visual impact stems from its heavy reliance on ultramarine pigment, as well as Klein's patent for a matte, synthetic resin that allows the pigment to maintain its brilliance and depth. Because of the unique way that the pigment reflects light, the color has a mesmerizing effect on the human eye. The color is not only used in the art and fashion world, but also for branding and web development projects.

The color #0837AC, a deep blue, presents accessibility challenges. Its low luminance can cause issues for users with visual impairments. To ensure readability, it's crucial to use this color with high-contrast text, ideally in white or a very light shade. Avoid pairing it with similarly dark colors, as this can make content difficult to discern. When used for interactive elements, such as buttons or links, provide clear visual cues, like a change in color or state upon hover or focus. Following WCAG guidelines for contrast ratios is essential to make websites and applications inclusive for all users. Consider using a color contrast checker to verify the contrast ratio between text and background colors meets accessibility standards. Moreover, using this color as a background for large blocks of text should be avoided, or at least paired with a very high contrast text color to ensure readability.
